No crash in evince or atril.
Thanks.

The cause for regression seems to be a technical issue not related to
poppler:
"Could not connect to ftpmaster.internal:80 (91.189.89.99), connection

Hello errors.ubuntu.com, or anyone else affected,
Accepted poppler into eoan-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/poppler/0.80.0-0ubuntu1.1 in a few
hours, and then in the -proposed repository.
Please help us by testing this new package.
Is there a chance that this will be fixed in Ubuntu Eoan?

** Description changed:
+ [Impact]
+ Selecting text in evince crashes for some files in eoan
+
+ [Test case]
+
+ Open the pdf in bug 1855596 and select some text.
+
+ [Regression potential]
+ This adds a check for a null pointer before using the pointer; it's limited
to a small function
Attached a test file, created by taking a screenshot, printing the
screenshot to PDF, and running the PDF through ocrmypdf.

The patch I sent upstream in
https://gitlab.freedesktop.org/poppler/poppler/merge_requests/280
does not look at the font name, so should not be affected by the issue.

Looking to the backtrace of the other report
font_name =
Looks like font_name can be null but the code doesn't handle that case

The segfault is in the code of the patch added by Julian to fix bug
#1830473
Julian, could you have a look to this regression?

Julian, could you also add one of those OCR generated PDF that created
the initial issue to launchpad? would make easier to test the patch in
newer versions

While the bug would be good to fix it's a bit too specific to qualify as
a release issue, tagging rls-ff-notfixing
