Xorg crashed with SIGSEGV in LogVMessageVerb()

[Kenny Strawn]

This bug involves the "LogVMessageVerb()" function that causes the X.org server to crash.

What I did to invoke this bug is run the Appearance Preferences to install the Impression GTK Theme. As soon as I unpacked the first theme in the Impression series, both X.org and the appearance preferences crashed.

[Bryce Harrington (bryce)]

Probably has more to do with the fact that we don't yet have a functioning fglrx for lucid.

[madbiologist (me-again)]

A new fglrx which supports the Xserver 1.7 used in Lucid has been released. See bug #494699 (particularly comment 20 and onwards) for details.

Can you please let us know if this fixes your bug?
