Hi,
thanks a lot for the report - but since we are about to release STK 0.7 (well, give or take a few weeks), and the code base has significantly changed (esp. new graphics library), we don't have time to investigate problems with stk 0.6* anymore. A quick look at the stack trace seems to indicate that the problem is related to snprintf (and potentially caused by a translation - so that's why we never saw that problem). In 0.7 we don't use snprintf there anymore, so all should be fine
And yes, a valgrind run is still on our todo list (and we actually do have a ticket open re going to fullscreen mode).
Of course I don't want to stop you doing a valgrind run on our current trunk
Cheers,
Joerg
