kaffeine 3.5.13.2 : Fix closing during saving session kaffeine R14 : Fix closing during saving session |
||
The bug strongly reproduced on logout with opened kaffeine window. And after that kdesktop_lock also hang: (gdb) bt #0 0xb62c4e12 in do_sigsuspend (set=0xbfbc5e04) at ../sysdeps/unix/sysv/linux/sigsuspend.c:63 #1 __sigsuspend (set=0xbfbc5e04) at ../sysdeps/unix/sysv/linux/sigsuspend.c:74 #2 0x0807d15b in main (argc=Cannot access memory at address 0x8 ) at /usr/src/debug/kdebase-3.5.13.1/kdesktop/lock/main.cc:358 Very interesting. When I started looking for some information on this bug, I found several of the same cases in other DE: XFCE on Fedora: https://bugzilla.redhat.com/show_bug.cgi?id=891737 Compiz on Ubuntu: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/754059 KDE4 on OpenSUSE: https://bugs.kde.org/show_bug.cgi?id=282441 Created attachment 1105 [details]
kaffeine 3.5.13.2 : Fix closing during saving session
Because the bug was repeatedly traceable in cooperation with kaffeine, I tried to fix closing kaffeine during saving session. With the attached patch crash stopped for me.
Incidentally, during the previously mentioned crashes I have seen openned multiple session logout status dialogs. This could indicate that there is sometimes really stopping sessions invoked multiple times.

Next I test it on KDE 3.5.10 and old XOrg sever and here I have not the problem. > Pushed to GIT in hash 56137a13 and also into v3.5.13-sru branch.
