Tuxguitar 1.3.2-4 hangs on startup

Tuxguitar 1.3.2-4 is hanging on startup on fully updated 32 and 64-bit systems, before even the splash screen is shown, producing the following error:

I was aware of the previous fix:

env SWT_GTK3=0 tuxguitar

so assume this is entirely unrelated.
Any solution most welcome.

Edit: Only solution found is to downgrade to package version 1.3.2-3

Re: Tuxguitar 1.3.2-4 hangs on startup

Hi, I had the same error. I fixed it by deleting the tuxguitar config folder ( ~/.tuxguitar-1.3.2). Worth a try.

Thanks for idea.
Have today fully upgraded system and installed latest package, tuxguitar 1.3.2-5
This requires jre8 as a dependency, so have let it install and now removed jre7 packages (as my other Java programs don't need them).
Tuxguitar seems happy all round now!
