Evolution Segmentation fault after upgrade to F17
Last modified: 2012-06-27 09:28:44 EDT
Description of problem: After upgrading my workstation from F16 to F17, evolution stopped working. I have tried to run it from the command line instead of main menu to see the output: It tried to migrate my data to the new format (I don't have the exact message, though), complaining that $HOME/.evolution/tasks is not empty, and segfaulting afterwards. I have removed the directory .evolution/tasks, and after that evolution printed that it tries to migrate the old data, followed by a segfault. Subsequent runs of evolution just end with "Segmentation fault", so I think the migration has succeeded and the problem is somewhere later. I am running XFCE session, not GNOME, FWIW. Version-Release number of selected component (if applicable): evolution-3.4.1-2.fc17.x86_64 How reproducible: 100 % (in my environment) Steps to Reproduce: 1. install F16, put some calendar data into evolution 2. upgrade to F17 3. run evolution from the command line Actual results: Segmentation fault Expected results: Evolution window should pop up Additional info: I use evolution mainly for calendar, not for e-mail. Running strace -f evolution reveals that one of the threads crashes after reading /etc/localtime: 3870 stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2246, ...}) = 0 3870 open("/etc/localtime", O_RDONLY|O_CLOEXEC) = 44 3870 fstat(44, {st_mode=S_IFREG|0644, st_size=2246, ...}) = 0 3870 fstat(44, {st_mode=S_IFREG|0644, st_size=2246, ...}) = 0 3870 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fe40005b000 3870 read(44, "TZif2\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\6\0\0\0\6\0\0\0\0"..., 4096) = 2246 3870 lseek(44, -1440, SEEK_CUR) = 806 3870 read(44, "TZif2\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\10\0\0\0\10\0\0\0\0"..., 4096) = 1440 3870 lseek(44, 2245, SEEK_SET) = 2245 3870 close(44) = 0 3870 munmap(0x7fe40005b000, 4096) = 0 3870 --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x1c} --- 3873 +++ killed by SIGSEGV +++ 3874 +++ killed by SIGSEGV +++ 3872 +++ killed by SIGSEGV +++ 3871 +++ killed by SIGSEGV +++ 3870 +++ killed by SIGSEGV +++ Installing debuginfos (debuginfo-install evolution) and running evolution under gdb does not make evolution crash, but it does not display any window either.

Thanks for a bug report. I do not expect the local timezone being an issue. This is crashing later in the code. could you print values of these variables, please: end dtend.value dtend.value->is_date instances_hold instances_hold->end_zone I suppose one of them is NULL, most likely dtend.value or instances_hold. Will evolution start in mailer if you run it there, please? You can do that by running evolution from console as this: $ evolution -c mail It should run, because the crashing operation is invoked from Calendar view.
In the meantime, I have upgraded evolution from the updates repository (to evolution-3.4.2-1.fc17.x86_64). It now displays the calendar, but the window is only partly drawn, and large areas are black. I will attach the screenshot. After few seconds of usage (switching to the next and previous weeks), it has crashed nevertheless. From the variables mentioned in comment #1, two are NULL: (gdb) print end $1 = 1339797600 (gdb) print dtend.value $2 = (struct icaltimetype *) 0x0 (gdb) print instances_hold $3 = (struct instances_info *) 0x222fc80 (gdb) print instances_hold->end_zone $4 = (icaltimezone *) 0x0 "evolution -c mail" works fine, but I don't have any mail accounts configured. I have tested that creating new mail pops up an editor window, the pull-down menu works correctly, etc.
Created attachment 593174 [details] Screenshot of calendar view (blur in the "task" area added by myself)
The black parts are supposed to be gray, I guess it's because of your Theme, evolution didn't read its colors properly, and defaulted into the black color (or is it a color your XFCE color theme?). Nonetheless, back to the crash, I moved it upstream as [1]. Please see [1] for any further updates. If possible, please CC yourself there, in case upstream developers will have additional questions. I guess the issue with the theming can be also filled rather upstream, as it doesn't seem to be Fedora specific issue. [1] https://bugzilla.gnome.org/show_bug.cgi?id=678856
OK, thanks for forwarding the bug upstream. I have added myself as Cc: to the upstream bug. As for the colors - I don't think I use anything non-standard: the menus and the whole mail mode are displayed correctly. However, I have just tested on another F17 machine, where I don't use evolution (so presumably there is a default configuration), that the black areas are not there in a calendar view. So this _might_ be something with my local settings.
Is the other machine running XFCE too? I think this is because non-gnome environment too.
Sorry for not mentioning that. Yes, the other machine is running XFCE as well. I don't use GNOME since the 3.0 thing.
Hmm, I see. That's interesting. Maybe if you could open a new bug report upstream, thus it's not forgotten about it, though if one machine works as expected and another not, then I'm afraid it'll be pretty hard to debug.
