Did you check that 'xdg-mime' is installed on the machine? Why is this an issue for Platform-IDE?

xdg-mime is indeed not installed.
But this environment is still a legal one for Eclipse Platform and is a typical one on CI, and the code that tries to invoke xdg-mime should be guarded to avoid such exceptions in case xdg-mime is not there.

We are seeing the same error on a Ubuntu 18.04 (in a Jenkins agent)
