Steps to reproduce:
1. Create a project that includes a Glade file.
2. Arrange for anjuta to open the file as an integrated project tab.
3. Shut down anjuta and start up again.

Other information:
This is on Fedora 10, a C++ project with a Glade interface file. On starting up, the splash screen appears and completes, then the app hangs with the splash screen still on display.

If the Glade file has not been opened on a project tab, the problem doesn't come up. The Glade file is for Glade 3, by the way.

Also, if the same project with the same setup is opened AFTER anjuta is running, no problem.
