Unfortunately I'm not a python guru so this is rather opaque to me. gdb itself doesn't provide a gdb.backtrace method, afaics. However, despite this message, gvim starts normally. And emacs-nox as well as many other CLI applications can be started just fine, too. But GDB hangs with emacs-X11 for some reason, even if I disable the python modules. From a quick GDB session it's not clear why this occurs :(I reported the problem upstream in a bugzilla entry already handling strange GDB hangs: https://sourceware.org/bugzilla/show_bug.cgi?id=17247
That bug appears to be something different. But I managed to fix the problem without actually understanding the code. I looked at cgf's patches from his build of gdb-7.6.50-4, and I noticed that some of his changes didn't make it into your gdb-7.8-1.src.patch. The missing ones are collected in the attached "cgf.patch" file.
If I apply that patch on top of your gdb-7.8-1.src.patch, the problem is gone. (The python warning is still there, but it seems to be harmless.)
