reassign to maintainer

Comment 2

Damir Shayhutdinov 2007-11-18 19:48:39 MSK

У меня не воспроизводится (Сизиф x86_64).

Предлагаю подождать до 2.2.4 - может там это исправят.

Пока предлагаю не заниматься быстротыканием в "запустить все/остановить все".

Comment 3

Konstantin Pavlov 2008-01-08 17:48:50 MSK

Проблема была в zeroconf-плагине.

Предлагается отключить его сборку во избежание.

Comment 4

Damir Shayhutdinov 2008-02-04 16:29:17 MSK

Проверьте в новой версии (2.2.5-alt1)

Comment 5

Damir Shayhutdinov 2008-03-29 13:09:04 MSK

У меня в новой версии вроде не воспроизводится.
