trunk: opening second document window corrupts default cursor in first document (rev >= 12476)

[su_v]

<quote>
After opening a new document (Ctrl+N, or selecting a template in the new dialog), the mouse cursor for canvas stays 'busy' in the original window (or - if it was new and not yet dirtied - in the current re-used document window) until a tool switch triggers a new cursor symbol to be used. The cursor symbol is misleading, since the main process is not blocked (inkscape is not actually 'busy').

Does not happen with older builds (< r12476) or stable.

Tested and reproduced with trunk on Ubuntu 12.04 (PPA), 12.10 (local build), 13.04 (PPA) and on OS X 10.7.5.

Confirmed on Windows XP, Inkscape trunk revision 12667.

Regression fixed in lp:inkscape r13528

Note: if the select tool was active in the original window, the cursor still doesn't update as expected (system cursor instead of Inkscape's cursor which changes when hovering a selectable object) - this happens in stable too, though, and is not part of the regression tracked here.
