New crash information added by DrKonqi
akonadi_davgroupware_resource (4.89.0) using Qt 5.4.2
- What I was doing when the application crashed:
- nothing... happens periodically, seemingly random...
- also happens at times when I am reading emails (hotmail on firefox)
- I cannot see any pattern in this, timing or activity, but it happens several times during a day and has become quite annoying.
Thank you,
Matt Z.

I'm going to take a closer look at this. Not new to Linux but am new to trying to learn and contribute more. Interesting thing about this bug appeared only after I configured my contacts using LDAP. I just now went back into Kontacts and had to manually "activate¨ contacts and restart the LDAP. So far, no crash. (In reply to Matt Z. from comment #3) > "Cannot connect to agent instance with identifier > 'akonadi_davgroupware_resource_8', error message: 'Could not get owner of > name 'org.freedesktop.Akonadi.Resource.akonadi_davgroupware_resource_8': no > such name'" This is because the resource crashed. > ./.config/akonadi/agent_config_akonadi_davgroupware_resource_8_changes.dat > ./.config/akonadi/agent_config_akonadi_davgroupware_resource_8 > ./.config/akonadi_davgroupware_resource_8rc So this resource has pending changes waiting, and one of them may trigger the crash. Don't delete these files just now :) Can you start "kdebugsettings", search for the dav resource (type "dav" in the search bar), restart it, and then paste here what's show in your ~/.xsession-errors (or ~/.xsessions-errors-:0 maybe)? Created attachment 97093 [details] ATT08610.xsession-errors OK, I hope I got the instructions right... I rebooted & had to set kdebugsettings again... here is the current .xsession-errors (no app crash). HTH.

This one is not containing anything that may point me in the right direction unfortunately. Created attachment 97097 [details] ATT93858.xsession-errors OK... rebooted again and this time the change in kdebugsettings "stuck", all other items unchecked (my untrained eye does't see much difference in the log)... had one crash, file attached. a note: neither file was changed during this time... I just let the computer sit idle. I noticed that at line 1078, there is an error (under Matt_Addr.vcf)... whereas at line 1100 there is no error (under Matt_Cal.ics). Kind of similar error around line 2899... still no changes in either file's data. I only had one crash (that I'm aware of) and at 3288 there is a crash message. Then at 3451 is the "Cannot connect to agent..." message.

I've updated to 15.12.2 but all mails regarding exchange calendar invitations still crash the resource.
Maybe I hit a different bug?

So I *guess* collection.remoteId() should be checked first...

Check mEtagCaches[collection.remoteId()] result before using it
The patch fixed the crash for me. However, I *do* think that it is a different issue, but at least you now know about it. ;-)
Thank you Grégory, I'm still trying to figure out how to tell when I get this update so I could report back with results or confirmation of fix... but because I don't know (as yet) if I have the update, I figured I'd wait a bit... while the crashes continued. Meanwhile, as of Feb 28th, since I was still having crashes, I did a bit more digging... I found a file -- .kde/share/config/akonadi_ical_resource_2rc -- which referenced an old/original calendar which was set up when claendar app was first loaded and subsequently deleted when I went with a single calendar using davgroupware (so the item/file referenced in this file did not exist)... as an experiment, I deleted the file and have had no crashes since then (no system updates have been installed since file was deleted). Normally I would have had 10-20 crashes by now, so it seems like deleting the file resolved the issue. System has been rebooted, both calendar & addressbook updates to phone work, and I do not seem to be experiencing any problems with either app or related data.
