I forgot to mention that you probably want to run the "configure"
script with "--enable-valgrind" which (according to the help message)
disables some timeouts to accommodate the valgrind slowdown factor.
With luck, that's what happened with the crash.  Note that valgrind
may report a lot of false positives that have to be sifted through.
Also, it will report issues in e.g. the Qt libraries which we have no
control over.

When fixes are made based on feedback from analysis tools, a mention
is usually made in the commit message.  Based on the commit messages,
I would say it's not too common.
