Interesting.  Maybe a buglet in Qt then?  My old openSUSE distribution
uses version 5.12.7...  Within the next weeks I have to eventually
upgrade my laptop to a new openSUSE version; will then test again.

Again, no pressure!  You have a lot of time to work on that :-)

OK, here is the backtrace at `continuous.cpp:152` as soon as the
breakpoint gets hit the first time (after loading `msyh.ttc`):

However, if I press 'continue' in gdb, it stops after one second again
at this place.  And again, and again...  Is this normal?  How shall I
ever test a change?
