On my system its quite simple to reproduce, start guile, type ,q enter,
then start it again and it crashes. In between runs Ive verified it does
not show up in the process list, ps aux|grep guile.

But doesnt happen every time. Seems like every other or every third time.

Here is a backtrace from gdb

Any other information needed? How can I dig more into why this is happening?
