[Inkscape-devel] Alert of missing X11 on OS X?

Hi all, this is actually not directly related to Inkscape but to the Mac OS X .app launcher, which I have borrowed for use in my own project (http://kymatica.com/algoscore). But this might be a bug that affects Inkscape users too:

I see in ScriptExec/main.c that it is supposed to show an error dialog if X11 was not found. This doesn't seem to be working, it just says "unexpected termination" or similar and crashes. I wonder about these lines:

// custom carbon events #define kEventClassRedFatalAlert 911 #define kEventKindX11Failed 911 #define kEventKindFCCacheFailed 912

I know nothing about Carbon or other OS X stuff, but should the first two really be the same numbers?

Unfortunately I don't have access to a Mac myself to investigate this.
