Selecting DXT1 Image Format When Nothing Is Loaded Causes The Program To Crash

[HurricanePootis]

System Information

Arch Linux QT 6.7.1 Linux 6.9.3

What happens

Whenever I open up vtfview, and I select DXT1 under Image Formats with nothing loaded, the program segfaults.

Backtrace

Thread 1 "vtfview" received signal SIGSEGV, Segmentation fault.
