1 add a new category; 2 save db; 3 click ok; crash
I could not reproduce this using either kphotoalbum 4.7.2 or 5.0. Can you provide a backtrace for the crash? Normally, you should automatically get a crash dialog (drKonqui) that helps with generating the backtrace...
I'm closing this bug because there is not enough info to reproduce. Feel free to reopen with more information...
