ALT Linux Bugzilla – #24024

На сизифе словил такое:
kernel: [63263.710834] lxpanel[30755]: segfault at 103500833010 ip 00007f924067fb47 sp 00007fff1f2af490 error 4 in libgtk-x11-2.0.so.0.2200.1[7f924037b000+508000]

Может будут мысли...

Словил то, после чего lxpanel у меня умирает!
Вот оно: (<unknown>:26789): GStreamer-CRITICAL **: gst_debug_add_log_function: assertion `func != NULL' failed
Теперь бы понять что делать :)

Значит, если падает действительно часто - самое время поставить lxde-lxpanel-debuginfo и держать lxpanel под gdb. Когда упадёт, в gdb сказать bt.

У меня не упал еще, но сегфолтнулся так:
Program received signal SIGSEGV, Segmentation fault.
0x000000000041e197 in task_draw_label (tk=0x8a6f80) at taskbar.c:313
313	        panel_draw_label_text(tk->tb->plug->panel, tk->label, name, bold_style, tk->tb->flat_button);
(gdb) 
Continuing.

Program terminated with signal SIGSEGV, Segmentation fault.
The program no longer exists.

Так сказать для истории.
