mythfrontend.real crashed with SIGSEGV in pthread_join()

[Joe]

Mythfrontend crashes on a regular basis (every other time) on startup. I cannot figure out what's wrong. Any help is appreciated.

On my backend server, running 0.25 fixes or 0.26 fixes, this happens consistently. I can neither open the frontend or the setup programme, which is a little inconvenient. The server is a quad-core headless, but i did try pluggin in a monitor and the same thing happened, so I don't think this is related to the headless nature of the machine. Is there a known workaround for this yet?

We really do appreciate you opening this ticket to help improve Mythbuntu, but it needs to be closed for a number of reasons. The biggest one is that upstream has moved on to a new version and believes this to be fixed. Could you please verify if this issue still exists in the latest version?

Please do not let the closing of this ticket dissuade you from opening a new ticket if this (or any other) problem occurs with the newer versions.
