OS:                Linux

when in plasmaengineexplorer i select amarok-* it crahses. i'm not sure this is an amarok bug and not a plasmaengineexplorer one, but selecting other engines like i.e. "time" it doesn't crash.

Is this still the case in beta2?

Comment 2 Giulio Camuffo 2008-10-30 22:00:32 UTC

do you mean amarok beta2? with kde and amarok from trunk and the bug is still here, except if i select the cloud and service engine. the other engines make it crash.
i' ve just noticed that i forgot to post the backtrace. here it is:
I selected the "current" engine

Comment 3 Giulio Camuffo 2008-11-06 22:52:51 UTC

update: i've just upgraded amarok from svn (880746) and the backtrace has changed sligthly:

Comment 4 Mark Kretschmann 2008-11-14 10:02:29 UTC

This should be fixed in SVN, as we're now using custom .desktop files that no longer conflict with Plasma.
