FTP app crashes when clicking ".."

[cybert79]

Hi alln

I am writing my first app for osx and have used QT and Xcode to get my code.
Now when I run my app and I click on .. for directory browsing the app crashes.
Can anyone help me?

@ASSERT: "!isEmpty()" in file ../../../QtSDK/Desktop/Qt/4.8.1/gcc/include/QtCore/qlist.h, line 287

(lldb)

line 287 :

inline void removeLast() { Q_ASSERT(!isEmpty()); erase(--end()); }@

Is the list empty by any chance when you try to remove an item?

Yep, thx Andre, you gave me the right hint :)

Question is: do you see how I arrived at that suggestion, based on your post?
