I don't think that the situation is that simple in my case.
Having enabled debug messages in enigmail I see that it gets stuck after the
following message:
2011-08-19 12:35:24.717 [CONSOLE] EnigmailAgentPath=/usr/local/bin/gpg
It is actually stuck in ipcService.runPipe() call after that message.

Having looked further it seems that the call is actually stuck in the following
sequence:
nsIPCService::RunPipe -> nsPipeTransport::Terminate -> nsPipeTransport::Kill ->
IPC_WaitProcess == _MD_WaitUnixProcess

In the _MD_WaitUnixProcess the following path is taken: FindPidTable returns NULL
and the thread gets stuck forever on PR_WaitCondVar(pRec->reapedCV, ...)

With ktrace I see that /usr/local/bin/gpg (which is actually a symlink to
/usr/local/bin/gpg2) gets executed, gpg2 prints some information and exits with a
status of 0.

I am not sure if this behavior can be explained by anything in the profile.
It rather looks like some possibly timing-triggered bug.
