Description Lubomir Kundrak 2007-04-26 11:04:09 EDT

Description a problem:

The recent update of libx11 package reportedly broke some packages
incorrectly using XCreateImage(), whose behavior was slightly changed
to return NULL in case it was passwd wrong parameters. This could lead
to a NULL pointer dereference crash in programs that did not check
the return value properly. Rdesktop is reportedly one of those.

Since Keyword Regression exists, this is a blocker,
not an exception.  Cleared exception flag.
Set blocker flag."
