Description Casey Dahlin 2008-07-28 10:43:43 UTC 
Upstart trunk is experiencing segfaults deep inside libdbus in Fedora Rawhide.

We have patches for bugs 15635, 15571, 15588, 15570 in our rpm, a patch which changes the default config file to allow a longer max timeout (no changes to actual code), a patch to the init script to start dbus earlier (again, no change to C code), a patch to Doxyfile.in that changes GENERATE_XML from NO to YES, one patch from git (attached) and one patch that attempted to fix this problem, with little success (the segfault has moved further down in the same function). That patch is also attached.

Also attached is a backtrace screenshot from a virtual machine. The backtrace is from code added to Upstart itself, not a native dbus

This one turned out to be NOTDBUS, right?  (If not please reopen)
