Ликс надо тоже обновить до 1.5.5 Тогда, всё работает. Думаю, погорячились ошибку закрывать.

Падает lyx-1.5.4-alt1 в бранче 4.1

Причем интересно заметить, если зайти на машину с бранчем 4.1 по ssh с включенным X-Forwarding тогда не падает :(

На локальной машине падает как-то через раз.

Если удалить ~/.lyx результат тот-же.

Наверно оно падает все в тойже /usr/lib/libQtGui.so.4

Можно посмотреть открыв в valkyrie
lyx под valkyrie работает, но там столько ошибок и утечек...

Если скопировать этот файл как ~/.lyx/session то у меня lyx перестает падать.

Действительно. В этом случае стартует. Но после падает если попытаться что-нибудь открыть. 1.5.5 - работает, почему бы не перенести?

Там как раз советуют обновить до 1.5.5. Текущая стабильная версия lyx-1.5.6.
Мне кажется, что есть много оснований собрать именно 1.5.6
Список изменений:

What's new in version 1.5.6?
----------------------------

** Updates:
***********

* DOCUMENTATION AND LOCALIZATION

- New (and complete!) Ukrainian localization of the user interface.

- Updated localization of the user interface for Czech, French, Galician,
  German, Italian, Polish, Portuguese and Japanese.


* DOCUMENT INPUT/OUTPUT

- New layout and template files for the Journal of Statistical Software
  (JSS).

- The importer for comma separated value (*.csv) files has been rewritten.
  Now the column separator character is automatically detected.
  Furthermore, the feature has been renamed to "Import->Table (CSV)".

- Paragraph line spacing settings are now imported when importing LaTeX
  files (bug 20).

- The paper orientation is now imported when importing LaTeX files.

- The paper layout and the number of text columns are now imported when
  importing LaTeX files (bug 4867).

- Add support for the xindy index processor (bug 4732).

- Add support for Graphviz Dot files (bug 4882).

- The A&A document class and template has been updated to conform to
  version 6.0 of the A&A specification (bug 4928).

- The 'Case' environment in the AMS classes has been rewritten to produce
  better output.


* USER INTERFACE

- Reenable quote display code, which was not working since 1.5.0.

- Implement properly word-movement code for both windows and mac
  conventions (bugs 2815 and 3580). This uses the new lyxrc variable
  \mac_like_word_movement, which is set to true by default on Mac OS X.
  It could be useful to emacs nostalgics too.


** Bug fixes:
*************

* DOCUMENT INPUT/OUTPUT

- Fix a LaTeX error with nested insets in CJK documents (bug 4913).

- Make sure that a GREEK SMALL LETTER SIGMA is not automatically turned 
  into a GREEK SMALL LETTER FINAL SIGMA (and vice versa) on LaTeX output
  (bug 4966).

- Fix LaTeX export of combining characters in utf-8* encodings (bug 4946).

- Output paper size information to dvi or pdf documents when using
  landscape orientation, such that viewers can properly display them
  (bug 2721).

- Fix encoding errors when typewriter font is used (bug 4727).

- Correct the kerning between two subsequent '<' or '>' characters.


* USER INTERFACE

- Fix crash related to the outline pane with some documents (bug 4857).

- Fix crash when clicking with middle button on a collapsable inset
  (bug 4662).

- Fix crash when an outlining function was used for a section inside an
  inset (bug 5004). These functions are now disabled for section that
  are not in the main text area.

- Fix input of numeric values in non-english locales (bug 4951).

- Fix display of filters such as "LaTeX (plain)" in the file dialog.

- Fix error navigation with the keyboard (bug 4895).

- When inserting an inset over a selection, do not copy the selection
  to clipboard if we do not intend to paste it later (bug 4977).

- When inserting an inset over a selection, do not remove space at
  start of paragraph (bug 2018).

- Allow the use of eqrefs in mathed (bug 4623).

- Fix shape of braces, '$', '%', '&', and '#', which where incorrectly
  shown in italics in mathed (bug 4320).

- Fix display of unknown math macros, which were incorrectly shown in
  italics (bug 2594).

- Use appropriate font in notes and ERT insets in section headings
  (bug 2477).

- Fix wheel mouse scrolling when it is set to "One screen at a time
  (bug 4972).

- Fix obscure 7 years-old bug with functions whose state can be toggled.
