[Bug 174991] New: digikam freezes when generating new tag

http://bugs.kde.org/show_bug.cgi?id=174991

So next step, as I wrote I have the problems also with the new database... a
bit of testing showed, if I remove the tagthumbnail before editing it works,
when there is a tagthumbnail assigned digikam crashes...

greets mike

Yes, you are right. Now I can confirm it again. When a tag thumbnail is set,
creating a subtag freezes digiKam... hmm...

Dont get distracted by crashes appearing on close when things should not be
closed at all. Enjoy this backtrace showing the place of the freeze:

SVN commit 887376 by mwiesweg:

Connect to thumbnail loader before calling getThumbnail, which can fire a
signal immediately.
Be paranoid and use queued signals so they cannot be released before entering
the event loop.
