From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.8.1.9) Gecko/20071105 Fedora/1.1.6-1.fc8 SeaMonkey/1.1.6 Description of problem: The program crashes during startup. Only error message received is "Segmentation fault". Version-Release number of selected component (if applicable): pavucontrol-0.9.5-0.4 How reproducible: Always Steps to Reproduce: 1. type pavucontrol in command prompt Actual Results: I see the window frame for a very short moment which after the message "Segmentation fault" is printed to console. Expected Results: Additional info: This is a fresh install of FC8 and KDE, so just about everything is still in its default configuration. I'm not familiar with tracing bugs, but anyway typing gdb pavucontrol >run shows lots of warnings about missing debug info and then finally this: Program received signal SIGSEGV, Segmentation fault.

Created attachment 260691 [details] gnome bug report for pavucontrol This happens for me, too. Attached is the bug report Gnome generated upon the pavucontrol crash.
Any word on this yet?
A little more information, to add on to what others have already posted. I recompiled pavucontrol with debugging symbols and ran it through gdb. Here's what I gathered so far: It crashes on line 848 of pavucontrol.cc: defaultSourceName = info.default_source_name The info structure: $2 = (const pa_server_info &) @0xbfc6e130: {user_name = 0x92236b6 "ianw", host_name = 0x92236be "media", server_version = 0x92236af "0.9.7", server_name = 0x92236a3 "pulseaudio", sample_spec = {format = PA_SAMPLE_S16LE, rate = 44100, channels = 2 '\002'}, default_sink_name = 0x0, default_source_name = 0x0, cookie = 2498977642} I'm guessing pulse doesn't have a default set, but I'm not sure how to correct this.
Well, I always configure my own kernel, and that plays some role on this bug. When I rebooted my machine with the FC8 default kernel, all went fine. So I took that config as a template and tailored my new kernel that I have used successfully. The config I was initially using was my own config that had been working on FC7. Bottom line is, there was something wrong in my kernel, but instead of giving me an error message, pavucontrol just crashed.
This has been fixed upstream in r68. I will shortly update Rawhide accordingly.
Fixed in rawhide.
