[Akonadi] [Bug 403058] Crash of akonadiserver upon startup

--- Comment #4 from Christoph Feck  ---
Minor Qt updates _can_ update internal API or data layout, and any code that
accesses the internal API needs to be recompiled against the new Qt. That's why
Qt's plugin system throws the version mismatch error, even if it cannot know if
there really is an incompatible change. Better safe (sane error message) than
sorry (just crash and nobody knows why).

For "normal" Qt code, you do not need to recompile.

No, I guess the package maintainers didn't think minor library version updates
required a rebuild. (I also find it a bit strange that a minor update is this
incompatible.)

In any case, I rebuilt akonadi and things are working again. I'll report this
downstream.

I did an update of Qt from 5.11.1 to 5.11.3 yesterday, and it seems this may
have something to do with it. Namely, I observed the following on the konsole
where I tried to start akonadi after it crashed:

org.kde.pim.akonadicontrol: ProcessControl: Application "akonadiserver" stopped
unexpectedly ( "Process crashed" )
org.kde.pim.akonadicontrol: Application 'akonadiserver' crashed! 1 restarts
left.
Cannot mix incompatible Qt library (version 0x50b01) with this library (version
0x50b03)
KCrash: Application 'akonadiserver' crashing...
KCrash: Attempting to start /usr/lib64/libexec/drkonqi from kdeinit
