Description of problem: Transmission crash with segmentation fault on startup Version-Release number of selected component (if applicable): 1.74 How reproducible: just install it from the rawhide repo and then run it Steps to Reproduce: 1.configure rawhide repo 2.yum install transmission 3.transmission Actual results: segmentation fault Expected results: transmission to run smoothly as ever :) Additional info: it doesn't help if you build it rpm yout self but it works perferctly fine if you build it from source and then run it ( I dont run make install just ./gtk/transmission). It is important to say that I make rpm and build from source 1.75b2 but there isn't so much of a difference yet. From the stacktrace I think it is glib2 bug as after I got it's debuginfo the stack trace changed into what it is now.

Michael: Thanks for the bug report! We're hoping to have 1.75 out in the next few days, so maybe we can get this fixed in time. I'm glad you've got gdb installed, that will make this much easier. :) The next thing to do is to repeat the gdb session in your original description, and after it crashes, run this command in gdb: "thread apply all bt" and then paste gdb's output into a comment in this ticket.

Thanks! 1. What locale are you using? 2. I suspect what's happening is that the tooltip string's length is exceeding the size of the static buffer I've allocated for it. Could you test the patch at http://trac.transmissionbt.com/changeset/9099/ to see if it's better, worse, or no change?
My locale is bg_BG.UTF-8 and the patch worked :). 10x very much :)
1.75 is in Rawhide now. Michael Stoykov, thank you very much for the bug report and thanks Charles for identifying and fixing the problem. Your help is appreciated.
