[Bug] Opening project, when other file/project is opened causes SegFault

[glpnk]

Operating System

Windows/Linux

What's the issue you encountered?

Opening project, when different project or file is opened, crashes ImHex (SIGSEGV).

File naming explanation:

• project: ImHex project with at least 1 file
• new [file]: non project file
• old [file]: file included in project

OS dependent things:

• Drag-n-Drop file order:
  • Windows: When selecting multiple files, the file you drag becomes the first one;
  • Gnome: files in alphabetical order (or depends on ordering method)

How can the issue be reproduced?

Pattern in project file not required.

Issue may be reproduced in different ways:

1. Drag-n-Drop "old" file and project
2. Open/Drop old file, then project
3. Open project, then open same project again

Sometimes opening new file, then project may crash app

Sometimes table in Pattern data window disappears
