Version: (using KDE 4.2.1) OS: Linux Installed from: Mandriva RPMs I'm using KDE 4.2.1 from Mandriva packages. But this problem happened from 4.1 I think. When I translated with lokalize, sometimes I used PageDown to move to the next entry, and lokalize crashed quietly. No error report dialog. So I tried to launch lokalize from command line, and turn on the core dump size. However, when it crashed, no core dumped. It returned "Alarm" then. Here are the last messages while crashing: lokalize(10500) KAiderView::approvedEntryDisplayed: approvedEntryDisplayed. entry: 162 approved: true lokalize(10500) Catalog::flushUpdateDBBuffer: updating!! KCrash: Application 'lokalize' crashing... Alarm All my unsaved work were gone. Even those translated entries were not recorded in the translation memory. I wondered if this problem was related to the translation database. I installed qt4-database-plugin-sqlite-4.5.0-1mdv2009.0.
which platform do you use? (64-bit or 32-bit). there was similar report #185144 , with Qt 4.5 on amd 64. never could reproduce it though.
Yes, similar, but a bit different. I got SIGALRM instead of SIGABRT, and no backtrace. I'm using 32-bit system. Well, maybe not SIGALRM? I don't really mean what "Alarm" meant.
i'm sure this is Qt 4.5 related bug. if you compile Qt 4.4 yourself and install it locally (+ madify LD_LIBRARY_PATH to make your system search in local dir first), Lokalize will stop crashing. I know at least one Qt 4.5 related problem that was fixed in branch svn (i.e. KDE 4.2.2) (bug 187219), so compiling lokalize from svn might help. Also, as you're already using Qt 4.5, you might want to compile kdelibs+lokalize from trunk to get autosave feature (at least you won't loose a lot of data anymore).
of course, if you see the crashes are reproducible on certain entries of certain files, do send me them.
I found a way that may reproduce this problem easier. For a file that contains many fuzzy or untranslated entries, if I push and hold alt-pgdown (or alt-pgup) to go through the untranslated messages, it would crash sometimes. Pushing and holding ctrl-pgdown or ctrl-pgup was similar.
which lokalize version do you you use? you can try running lokalize under gdb: 'gdb lokalize' <enter> r <enter> (got a crash) bt <enter> also try compiling lokalize yourself, this will add debug info to the executable http://userbase.kde.org/Lokalize#Compiling_Lokalize_from_trunk_under_KDE_4.2 (but checkout form 4.2 branch, not trunk)
this is most likely a dup of #191122 .
Not sure. The symptom was not quite matched, but we can see if it could be fixed in KDE 4.3.
how often do experience such crashes?
Quite often... maybe one fourth or one fifth. Just experienced another crash 15 minutes ago... *sigh*
