Also I noticed that a few seconds before it crashes all the resources in the list go blank (text and icon disappears, but they still take the space), while (some of) the Projects stay. I managed to crash it in the same manner again by just manually syncinc Nepomuk Tags (for KMail) in Akonadi Console. This crashed both KOntact immediately and Zenshin as described above. Created attachment 61398 [details]
console output
Console output from start to crash.
I can reproduce the same in Kontact/KOrganizer 4.6.0. For the record, from your description it sounds like something not specific to Zanshin (as you experience similar issues with korganizer apparently). When korganizer crashes, that would be useful to have its backtrace as well. Also your backtrace seems incomplete, it stops at frame 6 would be useful to have a complete one, I guess you're not running a debug build right now. Last but not least, I've been unable to reproduce that behavior so far. It sounds like we miss a piece of the puzzle at the moment to go further. If you get korganizer backtrace, and more complete zanshin backtrace, or more precise information to reproduce reliably, please let us know. I'll try to get a better backtrace soon and upload it. OK, I here's how I can replicate the issue using Kontact (Zanshin is running as well): 1) edited an existing ToDo in Kontact and added a category to it (it didn't have one before) *** at this point the resources disappeared from the resource list in Kontact's calendar view *** 2) repeated step 1) a few times; *** at this point Zanshin crashed, but not relevant for what I was testing *** 3) refreshed my IMAP folders in KMail (could be unrelated); 4) edited an existing ToDo in Kontact and changed its title; *** at this point Kontact stopped being responsive and started to consume 100% of CPU*** 5) waited for an hour or so; 6) put it out of its misery by killing Kontact. Managed to replicate it as well by running just Kontact and: 1) edited some titles of ToDos; 2) changed the category of some ToDos; 3) deleted two ToDos; *** Kontact starts eating up 100% CPU now *** 4) waited for 10 minutes or so; 5) killed Kontact with SIGSEGV to get a backtrace Note: in the first example I edited only the Kolab resource and in the second example only a local resource. Also in the second example I didn't look when the resource list got garbled. So, it seems it's not a Zanshin(-only) thing, but could be a lower level problem. I don't know what causes it yet though :\ Kontact's backtrace from example no. 2 in comment #7: Application: Kontact (kontact), signal: Segmentation fault [Current thread is 1 (Thread 0x7fa45c39b760

Upgraded to: * Zanshin 0.2_beta2 * KDE 4.7.0 * KDEPIM 4.7.0 (of course) * akonadi-server 1.6.0 ...and now the bug seems to be gone. I'm resolving it as FIXED and will reopen it if I manage to somehow trigger it. Possible related bugs: bug 291829, bug 276451 |
