mythtv-setup.real assert failure: *** glibc detected *** /usr/bin/mythtv-setup.real: malloc(): memory corruption: 0x0000000001768480 ***

[JanCeuleers]

Attempting to run mythtv-setup -O ThemePainter=qt over an ssh -X connection causes myhtv-setup.real to crash with a memory corruption error.

The problem also occurs if I don't specify the Theme Painter manually (Michael T. Dean suggested that I do so).

Mythtv-setup works fine when I go over to the machine and run it there.

I got hit with this Issue too. I suspect a common factor is that X server to which mythtv-setup is being forward is hosted on 12.04.

The Problem only arose after and update on the the mythtv client side to 12.04 from 11.10, The server is (for now) still an 11.10 host.

The client and server are on the same machine. when not being used. the mythtv server crashed on its own.

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.
