With Proton 5.0-1 the GUI of WInetricks won't open. It always exits with a symbol loopup error in libsoup:

$ winetricks --version

With any older Proton version this is no issue.

Works for me both with a Wineprefix created by Proton 5.0 and one upgraded from 4.11 to 5.0.

$ winetricks --version

$ protontricks --version
protontricks (1.3.1)

I recently had a file conflict with system updates that caused Steam to stop working with a file that should not even have existed where it was. Brief research shows one possibility for this error is conflict so you could make sure libsoup-2.4.so.1 has no conflicting duplicates.

On my system there's only these which are correct:
/usr/lib/libsoup-2.4.so.1
/usr/lib64/libsoup-2.4.so.1

If you have any others then the others with only that exact name should be incorrect.

There are other possible reasons though. Proton isn't necessarily at fault.

I have only this ones:

/usr/lib/libsoup-2.4.so
/usr/lib/libsoup-2.4.so.1
/usr/lib/libsoup-2.4.so.1.8.0

I would guess your system zenity is trying to use Proton's glib instead of your system's. The fix is probably something like protontricks should empty LD_LIBRARY_PATH before invoking zenity.

@aeikum I tested is with plain winetricks and that GUI works, so you seem to be right. I'll close this issue and open a new one at protontricks repository.
