For me the problem did not show up immediately after switching to the new Kolab ressource. The new ressource worked for some weeks... Now it crashes reliably. the output is: [...] akonadi_kolab_resource_1(8051)/kdepimlibs (kimap) KIMAP::LoginJob::handleResponse: "Login" "A000002" akonadi_kolab_resource_1(8051)/kdepimlibs (kimap) KIMAP::LoginJob::~LoginJob: KIMAP::LoginJob(0x1121f80) akonadi_kolab_resource_1(8051)/libakonadi Akonadi::EntityListCache<T, FetchJob, FetchScope_>::processResult: "Item query returned empty result set" Qt has caught an exception thrown from an event handler.

This happens in line 219 in kolabhelpers.cpp (v4.14.3). In a debug build, the "Q_ASSERT(item.hasPayload<KCalCore::Incidence::Ptr>());" (line 218) fires. So the expection is thrown while trying to access the payload afterwards.
The reason is that a non-existing item is processed here.
Query Debugger says:
21587: SELECT PimItemTable.id, PimItemTable.remoteId, MimeTypeTable.name, PimItemTable.rev, PimItemTable.remoteRevision, PimItemTable.size, PimItemTable.collectionId FROM PimItemTable INNER JOIN MimeTypeTable ON ( PimItemTable.mimeTypeId = MimeTypeTable.id ) WHERE ( ( PimItemTable.id = 86977 ) ) ORDER BY PimItemTable.id DESC
Success: Query took 1 msecs
Fetched 0 results
Using debug output, I have confirmed that 86977 is the id of the item that fails in the assert.
I just don't know where this id comes from, i.e., why this id should be accessed at all. It is possible that I created an item with this id (it's a "recent" id) locally, and deleted it afterwards, while I was offline. I could imagine that now it's still in some jon cache or similar for whatever reason, and the resource tries to send it to the kolab server. But I could not find the id anywhere in a table. (I don't know about caches.)
As a workaround, I replaced the assert by
if (!item.hasPayload<KCalCore::Incidence::Ptr>()) {
ok = false;
return Akonadi::Item();
}
Using this modification, I could avoid the crash. Then akonadi_kolab_resource could start and sort things out. Afterwards, I reverted to the original version of akonadi_kolab_resource (that crashed beforehand). Now the problems seems to be solved for me.
This bug has never been confirmed for a KDE PIM version that is based on KDE Frameworks (5.x). Those versions differ significantly from the old 4.x series. Therefore, I plan to close it in around two or three months. In the meantime, it is set to WAITINGFORINFO to give reporters the oportunity to check if it is still valid. As soon as someone confirms it for a recent version (at least 5.1, ideally even more recent), I'll gladly reopen it. Please understand that we lack the manpower to triage bugs reported for versions almost two years beyond their end of life. Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.1 aka 15.12; preferably much more recent), please open a new one unless it already exists. Thank you for all your input. |
