Re: Help with fdo#60471
I tried using the catch/throw stuff in GDB for debugging, gave up, and now simply set a breakpoint in the constructor of the Exception object :-) Works for me.

Help with fdo#60471
Hi guys! I was trying to solve this issue, but I need some code pointers... Can you guys point to me some places to start? And one more thing, there is a place for learn how UNO works and how this is used inside LO? I believe UNO is used in every case that we handle files right?

Hi Kendy and list! This is the point where we get this issue: // finally, parse the stream to a hierarchy of // SVGGraphicPrimitive2D which will be embedded to the // primitive sequence. Their decompositions will in the // end create local low-level primitives, thus SVG will // be processable from all our processors xParser-parseStream(myInputSource); I will take a look at this more closer, and try to understand why this happens Thanks a lot Kendy for the tip about debug=true!! 2013/2/12 Jan Holesovsky ke...@suse.cz Hi Marcos, Marcos Souza píše v Út 12. 02. 2013 v 16:04 -0200: I was trying to solve this issue, but I need some code pointers...
