[Bug] `libreport-plugin-ureport` is unable to submit `python3` reports, because some `exception_name` (or `desktop`) “do not match `'^[a-zA-Z0-9_\.]+$''`”.

[beedell-roke]

Evidence

When reporting via gnome-abrt-1.4.3-8.fc43.x86_64, or abrt-2.17.8-1, I observe:

--- Running report_uReport ---
Server responded with an error: 'Element 'exception_name' is invalid: String '                  self.window.pluginview1, self.window.pluginview2)' does not match the pattern  '^[a-zA-Z0-9_\.]+$''
('report_uReport' exited with 1)

Placement

Previously reported at abrt/abrt/issues/1688. However, the error message moreso implicates libreport-plugin-ureport-2.17.15-9.fc43, so I have re-filed it here.

[beedell-roke]

This reproduced in quite a unique manner, recently:

--- Running report_uReport ---
Server responded with an error: 'Element 'desktop' is invalid: String '/usr/share/wayland-sessions/plasma.desktop' does not match the pattern  '^[a-zA-Z0-9_/-]+$''
('report_uReport' exited with 1)
