Here is how I reproduced it with Inkscape 0.47 r22583 on Mac OS X 10.6 0) gdb Inkscape in /Applications/Inkscape.app/MacOS/ 1) open new document 2) draw freehand lines (sorry I didn't realize you have a different curve button, I thought of this one as curve. Might be the confusion right there...) alt + p 3) drag-click, release 4) alt + s for cursor 5) control + d for duplicate 6) shift + right arrow for move to the side. 7) repeat 4x, on the 5th freehand line/curve, inkscape crashes: "Inkscape encountered an error" 8) click "Close" 9) type bt enter but this didn't give me info like when I did the same thing in Inkscape in Ubuntu. Here is the gdb for this though: gdb) run Starting program: /Applications/Inkscape.app/Contents/MacOS/Inkscape Reading symbols for shared libraries .+++++++....................................................................................... done Reading symbols for shared libraries . done Reading symbols for shared libraries ...... done Warning: AppleCollationOrder setting not found, using AppleLocale.

If you can reproduce this crash, please file a bug at www.inkscape.org with a detailed description of the steps leading to the crash, so we can fix it. bt Program exited normally. -------- I will do this again in Ubuntu in another few hours as I have some work to get back to, but thanks for the quick response guys that was awesome. :-) ~R On Sun, Jan 10, 2010 at 4:21 AM, ~suv
