This bugreport seems to only really describe broken behaviour of c2esp. Yes, it smells quite strongly of being _caused_ by some bug in ghostscript, but when only proven breakable in an environment created inside of c2esp, it seems more sensible to me that this bugreport is tied to c2esp rather than ghostscript. @Didier: Since you reassigned this to (only) ghostscript, would you please consider re-reassigning to (only) c2esp instead? Reason I ask is that ghostscript is now security-buggy in testing since a month, seemingly blocked only by this issue. If reassigning does not seem sensible, then how about lowering severity (maybe only temporarily)? - Jonas -- * Jonas Smedegaard - idealist & Internet-arkitekt * Tlf.: +45 40843136 Website: http://dr.jones.dk/ [x] quote me freely [ ] ask before reusing [ ] keep private
