Bug 313271

Application: krecipes (2.0-beta2)
KDE Platform Version: 4.9.2
Qt Version: 4.8.3
Operating System: Linux 3.5.0-21-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
Selected 'Ingredient Matcher' in left set of tabs. I selected 'Italian salad dressing' from the ingredients list.  I clicked the right arrow button.  I double clicked on the 'Amount Available' column.  The 'Enter amount - Krecipes' dialog popped up.  I used drop down list to select 'fluid once'.  I entered '12' in the amount. I clicked 'OK' button.

The crash can be reproduced every time.

-- Backtrace:
Application: Krecipes (krecipes), signal: Segmentation fault
