cannot open tracker file (.trk or .trz)

I have a problem that happens often. When saving the file, it opens normally later.
At some point and when the project becomes more complex, it can no longer be reopened. Stays open at 92% or 95%
The only difference between the one that opens successfully and the one that can no longer be opened is that the original does not have a perspective filter applied.
To review the case I think it should be enough with the .trk files without the images

.trk file that opens up to 92%

Thank you

the footage is imported as frames, a JPG image sequence. This is not a XUGGLE related issue.

Some news trying to reduce the variables about this issue:
1- Start a new project
2- Import one of the uploaded image (not a sequence) just one .jpg image
3- Save Tab
4- Close Tracker
5- Try to open the saved tab...
Just a wheel spinning forever and Tracker's empty window. No matter in which PC (3 and counting)

Hi Fernando,

Can you zip the trk and video together (or easier yet open the trk in Tracker and save as a TRZ file) and share it with us? I can't test the perspective filter issue without a video (image files in your case).  Thanks. Doug

PS the second issue you discuss, that Tracker won't open a trk with a saved image video, is fixed in the next release.
