Hi Nick, and thanks for your quick reply. Here is the requested info:
1. Mac OS version: latest Lion (10.7.2)
2. Format exported: I don't get the chance to pick a format, the app crashes before that. My exact steps to reproduce a crash consistently are:
a. Lauch Art Text
b. Create a new document from any template
c. Click the "Export To..." button
d. Click "File..."
The app crashes instantly and consistently, just after that last click on "File...".
Note: I used "AppCleaner" to totally remove the app, then reinstalled it from the app store. It is still consistently crashing with the steps above.
3. It is not related to my document: it happens consistently with any new document from the template gallery.
4. Console log and crash log: may contain private info, so I will send them by email.
Note: I have a slightly non-standard setup (but not uncommon) where my user folder is on a secondary drive. So my "user" folder under "/Users" is actually a symbolic link that points to the real folder on the secondary drive. It has caused problems in the past (with Pixelmator, see this thread: http://support.pixelmator.com/viewtopic.php?f=5&t=6758)
But it may not be related this time, as I could reproduce the same error under a brand new user with a regular home folder.
Thanks for your help!
