The backtrace does not show any reference to KMyMoney specific code (except the first routine in frame #39). Does the problem also show if you use the Oxygen theme?

Didn't even notice Fedora had switched the widget theme. I switched back to
Oxygen and can confirm that exactly the same occurs. Specifically, KNotify
crashes a second or two after clicking Tools > Consistency Check. The
consistency check windows then works absolutely fine. The KMyMoney crash
then occurs by clicking Edit > Find Transaction > Date tab. I initially
thought it crashed at random after switching to that tab, but have now
narrowed it down to opening the datepicker widget and clicking the year.
Sometimes just clicking to enter a year causes a crash, other times it is
after pressing enter to navigate to that year.

Can you provide a backtrace using Oxygen as well?

KMyMoney crash with Oxygen widgets

Can you provoke the crash also, when you do exactly the same (selecting the year) when you use a different data picker (e.g. one for a schedule or transaction)? It is really strange, as the three backtraces you sent all show different scenarios. Can you try to upgrade to KMyMoney 4.8.0 (though I don't think it should make a difference but one never knows)?

comment #4 is a crash not uncommon when using phonon-vlc backend, where both Qt4/Qt5 get pulled into the same program space.  I thought fedora/rpmfusion vlc packages were fixed to prevent this happening, but alas apparently not.  Fixes/workarounds include:
* use phonon gstreamer backend (or uninstall phonon-vlc)
* run: /usr/lib64/vlc/vlc-cache-gen -f /usr/lib64/vlc

The others are odd too, but perhaps some pixmap cache refresh could help, try:
$ rm /var/tmp/kdecache-$USER/*.kcache

(In the meantime, I'll work on kmymoney-4.8.0 updates for fedora)

The KMyMoney crash does occur with all date picker widgets, not just the Find Transaction one.

Regenerating the VLC plugin cache worked to sort of fix the KNotify crash (KNotify no longer crashes, and a sound of some description is now emitted, a very garbled version of the usual dialog box sound). It's clear that the two crashes are completely unrelated (KMyMoney still crashes even now that KNotify is fixed), but initially I thought there may have been a chance they were related.

Clearing the pixmap cache, however, made no difference to KMyMoney's crash on entering a year into the date picker widget. I'll try updating to 4.8.0 in case that fixes things.

4.8.0 still has the same bug.

What widget style are you using (if other than default breeze)?

I have tried with Breeze initially, then switched back to Oxygen, and the crash occurs consistently with both.

Is this still present in 5.0?

Nope - seems to have been fixed in 5.0.0

Thank you for the crash report.

As it has been a while since this was reported, can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved.

I have set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved/worksforme" when you respond, thank you.

As I said above, this seems to have been resolved in 5.0.0 and above.
