I have done some debugging on this. I inserted
printf("output plugin activated for clipboard: %s\n",
(*out)->get_id());
at line 1202 of src/ui/clipboard.cpp.
The routine ClipboardManagerImpl::_onGet is called repeatedly (presumably
triggered by an external program creating a clipboard read request), with
different possible clipboard formats.
In my case, I was running Matlab and Teamviewer, and the following clipboard
requests were tracked over a 10 second period:
output plugin activated for clipboard: org.inkscape.output.svg.inkscape
output plugin activated for clipboard: org.inkscape.output.png.cairo
output plugin activated for clipboard: org.inkscape.output.svg.inkscape

As can be seen, the repeated requests cause Inkscape to try and export the
copied data every few seconds, in multiple formats.
Some of the formats cause errors, for example
org.ekips.output.hpgl
org.inkscape.output.plt
So one temporary workaround to prevent the error dialogs is to remove
those extensions:
cd /usr/local/share/inkscape/extensions
files="
gimp_xcf.inx
dxf_output.inx
hpgl_output.inx
jessyInk_export.inx
plt_output.inx
sk1_output.inx
svg2fxg.inx
svg2xaml.inx
ink2canvas.inx
"
for x in $files ; do sudo mv $x $x.disabled ; done
(you may need to do this in /usr/share/inkscape/extensions, depending on
installation).
However this doesn't fix the underlying problem, and inkscape is still silently
exporting the clipoard many times a second in many other formats.

Bug description:
UPDATE: After further investigation it turned out to be a problem related to
the copy operation, in combination with a totally unrelated running Java
program (FreeRapid).
Reading some followups and other bug reports, it seems to be caused by the
new clipboard management system (introduced as a fix for the bug #170185), as
reported in bug #421597.
The routine ClipboardManagerImpl::_onGet is called repeatedly by an
external program, with different possible clipboard formats, causing
Inkscape to try and export the copied data every few seconds, in
multiple formats.
So far these applications are known to randomly trigger an input/output
extension (on linux):
- FreeRapid Downloader
- jDownloader
- xfce4-clipman-plugin 1.1.3
- Netbeans
- xfce4-settings-helper (Xfce 4.8)
- Team Viewer (teamviewerd 10.0.36)

The original report was this:
I'm getting this error when I try to edit a text object created previously
with a font that's not available in this system.
It looks like Inkscape has problems to resolve the font substitution and
displays the error message in a popup window that keeps appearing again and
again, leaving no other remedy than closing inkscape and reopening it.
The error message is attached.
