x11-libs/libX11 version?
x11-libs/libX11-1.1.1-r1
Hmm, I guess it works when you downgrade to 1.1.1, right?
Yes, downgrading to the unstable 1.1.1 seems to solve the issue.
Bleh... see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=418021
From: https://bugs.launchpad.net/ubuntu/+source/rdesktop/+bug/102922 Specifically comment 9: https://bugs.launchpad.net/ubuntu/+source/rdesktop/+bug/102922/comments/9 The solution provided in comment 9 works for me. I will attach a diff against the 1.5.0 sources and also a diff to get an updated 1.5.0-r2 ebuild.

Created attachment 116463 [details, diff] Fix for segfault caused within rdesktop-1.5.0 Fix for segfault caused within rdesktop-1.5.0 as a result of libX11-1.1.1-r1
Created attachment 116465 [details, diff] patch for new ebuild 1.5.0-r2
I can confirm the attached fix works as rdesktop-1.5.0-r2 in my environment, in which I use it quite heavily.

I have had the problem and the patch fix it too.
echo >x11-libs/libX11-1.1.1 >> /etc/portage/package.mask emerge libX11 rdesktop
Ehh, no. Fixing rdesktop and using the patch above is much preferred to allowing a security vulnerable version of libX11 on your machine. This should be taken care of soon.
The ubuntu path replaces the cx * g_bpp /8 .., it will segfault again btw when the XCreateImage decides to return a NULL again...., So a path should also include a check for the XCreateImage result value imho.
I have accepted wolf31o2's offer of maintainership and committed rdesktop-1.5.0-r2 to the tree. Please test, and if no issues are found, I will file a stabilization request in 30 days.
1.5.0-r2 has been working fine for me.
