Package: qtcreator
Version: 4.8.0-1
Severity: normal

--- Please enter the report below this line. ---

After upgrading to qtcreator 4.8.0-1, I experience qtcreator reproducibly 
"freezing" during startup.

Starting qtcreator using "qtcreator -profile" revealed that the "Help" module 
is the last one that is loaded so I tried starting qtcreator with "-noload 
Help" and it starts correctly. In that case I do get a segfault later on when 
I quit qtcreator, but that's probably unrelated.

I also use some of the Clang related plugins (just mentioning this in case it 
might be relevant).

Cheers,
  Johannes

Thanks *a lot* for all this.

I think it might be, that or some corrupted file (the db maybe?). So far no 
one else reported the bug, so I'm inclined to a config issue.

Closing the bug then.

Thanks again!
