Loading text with the first line ending with tabulator causes crash

[Zorki]

Hello,

i've got a program loading several text files and displaying the content using a QLabel embedded in a QScrollarea.
This works quite fine, except when I load a file thats first line ends with a tab. The Text file is still loaded correctly, but when resizing the Label or changing the Stylesheet of the Scrollarea I receive a segfault.

The Objects are all instatieated properly and I can also view other textfiles before producing the crash.


I have no idea, what the actual problem is, i don't even have an idea, what to search for, so maybe someone can give me a hand what to try next.
