[Inkscape-user] Directory path problem exporting to png in Ubuntu

When I click on the directory and choose a directory, add the file name and save, it exports to a directory /run/user/1000/doc/<8 character hexidecimal>

This then shows in the export file field with the entered file name at the end.

This morning a file saved correctly, later this problem occered and the files show in the correct directory but look like ".xdp_<file name>.ZDP701.

After my last attempts to correct the directory in the file field of the export window, the files dont even show in the directory or in the Ubuntu "Recent" directory, but exist in the /run... directory.

Is this an Inkscape problem, or do I have a rootkit, or both, or something else??
