Bug 137382

ARgh, I just submitted my passwort. Please censor it :-)
I have also changed it locally.

Sorry but I cannot do that, because I cannot edit your comments. I could only mark it as private and you'd have to edit it and paste it as a new comment without the password. ;)

market as private

OK, here is another copy (censored): :-)

Thanks!

Hello,

we use rdesktop (shipped with SuSE 10.0, v1.4.1) to connect to Windows terminal servers. This is to avoid having Windows locally on each PC. However, rdesktop seems to be very unstable.

One Windows 2003 Terminal server has a particular problem: rdesktop just crashes / quits:

~> rdesktop -T "Remote Desktop [XXX@getserver4]" -d GET -u XXXX -p XXXX -r sound:local -a 16 -B -k de -g 1274x970  -r disk:Home=$$HOME,Media=/media -r printer:hp_laserjet4l="HP Laserjet 4L",deskjet890c="HP DeskJet 890C",laserjet2300="HP LaserJet 2200 Series PCL"  139.11.161.161

This happens often when starting a program, exactly when the application startup logo appears (e.g. FEKO). It also happens when trying to save a file in any application, when the File/save dialog appears.

The problem only appears when using 16-bit color depth, which is however a requirement for many of our applications.

It won't happen with 8-bit depth, and no other combination of parameters has produced this crash yet.

Please investigate this.

Thank you! :-)

Please don't inline larger quantities of text here (more than ~20 lines), rather use the attachment feature instead. Bug reassigned.

I was unable to reproduce it here. I can send you a package with debugging
symbols if you want. 

Yes, please do! I tried recompiling myself, but I don't know what compile options you need. I'll happily to submit backtraces. I'd even let you test it out yourself if the machine in question were not behind a firewall.

Additional info from Jens:

The crash happens sometimes if a special application is started inside the
windows terminal server session.

Because I am unable to reproduce it I close this with "WORKSFORME".

Please reopen this bug if you have more informations (maybe from the 
rdesktop developers directly).
