--- Comment #25 from Luca Weiss <l...@z3ntu.xyz> ---
(I copied this comment from 390609 except that the backtrace also contains Qt
debug symbols and thanks Antonio for pointing me to the correct bug - I
searched but couldn't find this one)
I have debugged this issue a bit and found, that the
runners/bookmarks/faviconfromblob.cpp file in plasma-workspace tries to access
the table moz_favicons in the sqlite database (line 80) which doesn't exist
though.
Checking the firefox source code, I found mentions that since Firefox 37 the
table was not used anymore and since Firefox 41 the table was dropped. I have
no idea why this wasn't an issue before but it might be because of a newer Qt
version that broke something?
