I've seen this once as a spurious crash when running thoggen in gdb, but have never seen it since. I have absolutely no idea what might have caused it, the code in thoggen looks all sound to me, with the exception of using localtime() rather than localtime_r(), but I'd expect even that to be fine with glibc. I have now changed thoggen to use localtime_r in any case though if it's available (in svn trunk).
