Details

We now run leak tests without any kind of desktop environment services running. It seems that this triggers an intermittent hang in the leak tests when trying to get the system proxy settings. We can work around this by overriding the proxy settings in the profile, but it looks like there's some underlying issue that should be investigated.

A strace output would be useful. Even a strace -p $pid from when the firefox process is hanging.
There are two firefox-bin processes. One is blocked on a read() call to a pipe file descriptor. The second is blocked on a futex() call.
(In reply to Chris AtLee [:catlee] from comment #2) > There are two firefox-bin processes. One is blocked on a read() call to a > pipe file descriptor. That sounds like what is hanging. It would be useful to know what the other end of the pipe is. Checking files in /proc/*/fd would help (checking which one point to the same pipe)
Now that we have GIO (bug 713802), I checked whether we could remove the workaround. Looks like a similar issue, but still no stacks because the harness generated a minidump and there was "No symbols path given". https://tbpl.mozilla.org/php/getParsedLog.php?id=15608760&tree=Try#error1 I don't know whether symbols have even been generated at this point. The builds run at this stage are not stripped. We may still be falling back to GConf because there are no relevant GSettings schemas.
Ah, yes, GSettings are not available until GIO 2.26.
