Continuing.
Program terminated with signal SIGSEGV, Segmentation fault.
The program no longer exists.
On subsequent calls this usually does not happen as nlkt manages to
create directory before segfault. I tried to do similar thing with
arora and fet (both depend on libqtcore4) but they did not crash.
