Yes, it was 0.3 - I installed the lib and gweled for the first time. I tried reproducing it, but I was not "successful" ;-) Sometimes it happens during normal gameplay, sometimes when I get a bonus x2 - screen...
Then, it runs for 30 minutes without freeze...

I will try to launch gweled from xterm and pipe its output to a file, maybe I can get some information this way (and I haven't checked whether I can still ssh in and kill gweled btw)
