segfault on Fedora 33

Hello,
unfortunately the Linux binary segfaults on Fedora 33 straight after entering the file to analyze.

Python Exception <class 'AttributeError'> 'NoneType' object has no attribute 'type':

Seems to be issue with all the QT5 builds, The QT4 builds work ok.
Tested with :

• 0.4.0.3 ... OK
• 0.5.2 ... SIGSEGV
• 0.5.3.2 ...SIGSEGV

Hi,
Thanks for reporting. It seems just a Qt version incompatibility. PE-bear was built with an older version of Qt5 than the one you have installed. I will provide new builds soon, and for the future I will try to bundle PE-bear with the exact version with which it was built.

[xambroz]

Thank you.

Hi! Did you try the new builds: 0.5.4 ?
I tested it on Fedora, and while the version with Qt 5.12 indeed seqfaults, the version with Qt 5.14 worked fine for me.

I was using Fedora 34 for my tests though.
Please let me know if it works for you.

From now you can build Qt from the sources to avoid any of such issues: https://github.com/hasherezade/pe-bear
