Weird crashes on Mac using Qt 5.2.1?
-
We are developing a cross platform application using Qt 5.2.1 and recently we are seeing a large number of crashes on Mac with callstack that appears to have crashed in Mac API. The crashes seem to happen after user dismissed a window in our app but we have no luck reproducing the issue so far. Wondering if this is a known bug in 5.2.1? The user is running Mac OSX 10.9.

Hi and welcome to devnet,
To search a bug, you should go to the bug report system
Does the error report dialog give some more information about the crash ?
