Hi Mark, thank you very much for this bug report. It shows that somebody is using the print functionality in GNUstep. What you are doing is quite legitimate and GNUstep has to support it. I have tried to correct the problem you found in a slightly different way. Could you please have a go with current SVN source and report back, if it still fails? There will be a couple of further changes to the graphics context handling in the next weeks. I try to do this big change rather smoothly, but you already discovered the first error here. So please test this from time to time for new errors.
