Crash when combining paths

[LucaDC]

Inkscape crashes whenever I try to combine paths, both with ctrl-k shortcut and with the Path->Combine menu option.
Windows XP SP3, rev 13209.

To reproduce:
 - open new document;
 - draw one (or more) shape (e.g. a rectangle);
 - select it (or all of them);
 - press ctrl-k or select Path->Combine;
 - crash!

Reproduced with r13209 on OS X 10.7.5:

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0x0000000000000000

Regression was introduced between r13193 (ok) and r13202 (crash), full backtrace of debug build r13209 attached.

@Johan - could you take a look at this recent regression?

[Johan Engelen (johanengelen)]

Sorry for that. Dumb mistake, my testing apparently accidentally always had a style and patheffect applied to the first selected element.
Fixed in rev 13210.

@Johan - thanks a lot for the fix!

Thank you for the quick fix.
