Crash pango with italic characters

[sambo57u]

JabRef 5.0-beta.360--2020-01-21--7ddfd9f
Java(TM) SE Runtime Environment (build 13.0.2+8)
pango-1.44.7
Fedora Linux 31

When I open jabref with the attached bib file, it opens ok but when I try to use the scroll bar to scroll down about half way through jabref crashes with the message:

Pango:ERROR:../pango/pango-context.c:1434:itemize_state_process_run: assertion failed: (state->run_end != state->run_start)
Bail out! Pango:ERROR:../pango/pango-context.c:1434:itemize_state_process_run: assertion failed: (state->run_end != state->run_start)
Aborted (core dumped)

I am not a LInux expert and on Windows I cannot encounter a problem, but it might be related to Font stuff. E.g. Maybe there is a problem with the font or the Unicode-italic rendering in the form here.
Maybe one of the other fedora users can reproduce this problem.
But I would close this issue as it seems to be some javafx/linux problems which we can't do anything about here

[sambo57u]

It is related to unicode characters. I am not sure why you closed it since it core dumps jabref on a stable Linux distribution and core dump is always a bug!

[Siedlerchr]

Well, the problem is not in JabRef itself I think, but either in JavaFX or the pango library.
You better should report this bug to the pango team as this error dump is clearly related to pango.

You could try to change the Font in settings and see if that helps.

Hi, I narrowed it down to a single reference. The attached bib file crashes jabref every time. It seems like the latex sequence in Garc'{\i}a-Recio crashes jabref.

NOTE: Look at the actual bib file since the pasting into message missed a \

[sambo57u]

It is '{\i} that is making jabref coredump. Removing the slash works ok '{i}

[Siedlerchr]

@sambo57u Yes, that's what I suspected as well. It's the latex command for displaying text in italics.
Could you try to convert it using the latex2unicode formatter and test if that works?

[sambo57u]

Yes, using http://latex2unicode.herokuapp.com/ for interactive testing produces the correct dotless i
with French accent.

[sambo57u]

I guess this is passed to Pango after conversion that somehow leads to jabref coredump. Pango I have is the latest one. And as jabref I am using today's rpm build.

[Siedlerchr]

I think this issue is not in JabRef's , it's beyond our realm and we cannot do anything about this. Therefore I'm closing this issue.

Has anyone reported this issue to Pango? If so, can you please provide a link to it?

[Siedlerchr]

It might be fixed in javafx 15 (we plan to use that soon), at least there was something I read about pango

[Siedlerchr]

I just merged in the new javafx version. According to the changelog https://github.com/openjdk/jfx/blob/jfx15/doc-files/release-notes-15.md
this issue might be finally fixed

[sambo57u]

I can confirm that it is fixed! Thanks.
