Summary0001745: Mac OS X Graphviz Viewer crash upon file update
Description



Upon refresh by an external editor (TextWrangler and ed tested), the
GraphViz viewer crashes:

Additional Information

[akstarks]
Attached is recent stack b1804a.txt, and b1804.gv I was editing. The scenario is:
<CD>
1) editor (TextWrangler) with file open, making random changes
2) watching changes the changes being updated
</CD>

the behavior is to make change, write the file, eventually it crashes. I don't have a reliable method to crash it, yet.

looks like the likely culprit is in GVFileNotificationCenter.m
