nautalis opens *.rs (i.e. rust files) in multiple gvim instances as if the gvim.desktop file used %f but it uses %F

[Grizzly(Francis Smit)]

I select multiple files extension .rs and open it in gvim from the right click menu and it opens them in multiple gvim's this is the only file type showing this behaviour

1. I am using
$ lsb_release -a

3. I expected it to open *.rs files in one gvim like it does with every thing else

4. it opened them in one gvim per file

[Sebastien Bacher (seb128)]

the behaviour depends of gvim and of its .desktop entry

[Grizzly(Francis Smit) (grizzly-smit)]

Ok update if I try to open multiple *.cpp files (no headers) it opens them in multiple gvims, but if I select multiple *.pl's no such buggy behaviour

[Grizzly(Francis Smit) (grizzly-smit)]

I've checked the gvim.destop file and it clearly uses %F not %f also if it was that it would be consistent across file types
