Closing an externally modified file then attempting to reload it crashes CodeLite

[kchalmer]

Steps to reproduce:

1. Open a file in CodeLite.
2. Switch focus away from the CodeLite window and modify the file.
3. Middle-click the file's tab to close that file (without first left clicking on the CodeLite window to gain focus).
4. Select "Reload" in the "Some files were modified outside of the editor" dialog that pops up.
5. CodeLite crashes.

Reproduced with x86-64 build of ad6ff8d on Kubuntu 14.04.
