[dolphin from git frameworks]

When I launch an application form Dolphin (ie. clicking a text file opens Kate, or a picture opens Gwenview) Dolphin freezes 90% of the time making unusable.

After it froze I attached gdb and it showed the following:

(I do have libdbus-1-dev packages installed but don't get a more clear backtrace)


Reproducible: Always
