Crashes on text filter

Bug
1

I have a lot of crashes on the text filter. What can I do to further narrow it down? I am Running Linux Mint Cinnamon 64bit

2

Turn off GPU Processing:

I get the message: "The file you opened uses GPU effects, but GPU processing is not enabled.
Do you want to enable GPU processing and restart?"
I am not aware of any GPU effects in this project. There are only fade ins and outs.
A Catch 22?

The fades are using GPU filters. You have to recreate the project; there is no conversion. Or, you can edit the XML with a text editor to remove the filter blocks that contain the fades and recreate just those.

I removed all the filter blocks manually and then checked in the xml if they are gone indeed. The xml doesn’t contain the word “filter” any more. still it doesn’t open without GPU mode.
