Public bug reported:

Very frequently, but not every time, I get a multi second long busy
hang, when I copy code snippets to or from the clip board. SO farI have
observed this behavior only when I use Ctrl+C, Ctrl-X and Ctrl-V, but
not when I used the right click menu to perform the exact same action.
The hang leaves one CPU running at 100%, during that time qtcreator is
completely unresponsive, it does, nevertheless, remember actions (both
keyboard and mouse) done during that hang period and catches up when the
hang is over. This bug does not happen with other applications (I also
tested it with kate which is as similar as it gets).

I would welcome hints how to support the debugging of this issue and
can, if needed, compile and run test versions of qtcreator or required
software. dmesg and ~/.xsession_erros show nothing related to this
issue.
