A fatal crash can be observed while removing tools from Tools menu. To reproduce the crash do the following,
- Add a tool using Tools>Configure menu option and click OK. Now the added tool will be available under Tools menu.
- Delete the newly added tool using Tools>Configure menu option and click OK. Now C::B will crash.
The crash is not observed if:
- A separator is added & removed.
- If tool list is not empty.
The backtrace is as follows:
(gdb) run
