Comment 12 Jan Teichmann 2013-01-10 09:08:26 UTC 
I noticed more strange memory corruption in other programs recently and as it turned out I had a defective RAM module. Effects were very random and rare but could be the cause of most memory corruption I lately reported. I assumed it is related to the beta state of F18 so I didnt suspect the RAM at first but MemTest found a small address range with errors.
I am extremely sorry for taking up your time hunting down bugs which are most likely not there. I decided to close my latest bug reports as I can not assure that the memory corruption was actually caused by the program rather than the defect RAM module.
