Openshot 2 destroys Openshot 1 project files without backup

[David Kastrup]

This is particularly egregious since the PPA version of Openshot 2

a) overwrites the file associations
b) does this under the guise of "Openshot" rather than either "OpenShot 2" or "OpenShot Qt"
c) does an autosave after autoconversion
d) does not ask questions before overwriting previous project files
e) is too unstable and slow to work with older hardware
f) rewrites the file in-place

As a result, when you install openshot-qt in parallel to your existing OpenShot 1.4 and unsuspectingly click on an .osp file, you get offered "Open with OpenShot" as usual. If you click on it, /usr/bin/openshot-qt rather than /usr/bin/openshot gets called on the file and autoconverts it into its own format, overwriting the old file _in-place_. As a result, no undeletion utility is able to recover it. Nor does rewinding a meta-data journal on the file system help.

Just closing the accidentally opened OpenShot 2 without any change is enough to destroy the original project file.

As a result, one must _not_ even install OpenShot 2 for testing purposes as it will get called in unexpected situations without any possibility to prevent it from destroying existing project files in an inrecoverable manner even when you try immediately exiting it again.

This is a bad idea.
