Summary	0001139: FreeCAD crashes when changing placement of sketch.
Description	As above + the sketch is used to create pad. There are 4 holes int he pad created with LinearPattern. After the transformation linearpattern is no longer in the main pad area and that crashes FreeCad. Reproduce (not always): use placement to rotate Z to 0 on "Back Plate Sketch" in the attached file

jrheinlaender 2013-07-22 14:48 developer ~0003421	Could you please detail "As above + the sketch is used to create pad". What is meant with "above"? "After the transformation linearpattern is no longer in the main pad area and that crashes FreeCad." I couldn't reproduce that. After changing the placement of the Back Plate Sketch the holes move along nicely staying in the correct relative position

jrheinlaender 2013-07-22 14:50 developer ~0003422	But I did notice that double-clicking on the LinearPatterns which are subordinate to the MultiTransform will crash FC after closing the edit dialog. IMHO the solution is to hide these subordinate LinearPatterns so that they are not visible for selection.

jrheinlaender 2013-07-28 17:36 developer ~0003432	Please give more information on how to reproduce the crash

pfirszt 2013-07-31 19:46 developer ~0003435	I wasn't precise enough. "As above" was about the name of the bug report. I'll try to reproduce the bug and provide detailed step-by-step instruction.

pfirszt 2013-07-31 20:05 developer ~0003436	This is a recording of a short gdb session: http://firszt.eu/FreeCAD/FreeCAD_crash.webm For some reason I couldn't upload it to sourceforge. Let m know if that's enough (it might not be clear when I use double-click)

jrheinlaender 2013-08-01 04:19 developer ~0003437	See my comment above: But I did notice that double-clicking on the LinearPatterns which are subordinate to the MultiTransform will crash FC after closing the edit dialog. IMHO the solution is to hide these subordinate LinearPatterns so that they are not visible for selection. You should modify the sub-features of a MultiTransform through the MultiTransform dialog, not directly. There is a discussion about hiding the subfeatures in the tree altogether, see http://forum.freecadweb.org/viewtopic.php?f=10&t=2951&p=34019#p34019
