Bug ID: 390609
Summary: krunner / application launcher crashes because of
missing firefox favicons table
Product: plasmashell
Version: 5.12.1
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: Application Launcher (Kickoff)
Assignee: k...@davidedmundson.co.uk
Reporter: l...@z3ntu.xyz
CC: plasma-b...@kde.org
Target Milestone: 1.0
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?
$ sqlite3 .cache/krunnerbookmarkrunnerfirefoxdbfile.sqlite

If the backtrace from Qt is needed, I can recompile Qt with debug symbols.
