  Target Milestone: ---
           Link ID: GNOME Gitlab GNOME/pango/-/issues/627
    Classification: Fedora



Description of problem:
After upgrading to Fedora 35, nm-applet (from
network-manager-applet-1.24.0-1.fc35.x86_64) segfaults on a pango assert:
(nm-applet:8121): Pango-CRITICAL **: 19:26:36.541: pango_item_split: assertion
'split_offset > 0' failed


Version-Release number of selected component (if applicable):
pango-1.49.3-1.fc35.x86_64


How reproducible:
100%

Steps to Reproduce:
1. Left-click on nm-applet to get list of possible connections

Actual results:
Immediate crash

Expected results:
List of connections (note that some sections show small cap letters)

Additional info:
The linked gnome gitlab issue mentions this is generic for strings in string in
a GtkLabel (with small caps)

Rebuilding pango 1.49.3 with patch from
https://gitlab.gnome.org/GNOME/pango/-/merge_requests/505 fixes the issue

Sorry, I can't reproduce this issue yet.


This is the pango package scratch build with the patch.

URL: https://koji.fedoraproject.org/koji/taskinfo?taskID=79008333

If the above package works for you, I will include the patch in Fedora soon.

--- Comment #3 from mediaklan <mediaklan(a)gmail.com&gt; ---
I can confirm this issue since my recent upgrade to F35, using xfce.
- A left click (for example, disconnecting a vpn) will crash the applet.
Here's the segfault :
[70195.350282] nm-applet[10865]: segfault at 38 ip 00007f9f4cd91be8 sp
00007ffd4ab8c370 error 4 in libpango-1.0.so.0.4903.0[7f9f4cd86000+2c000]
And Pango-CRITICAL :
(nm-applet:167296): Pango-CRITICAL **: 22:04:08.125: pango_item_split:
assertion 'split_offset > 0' failed

Thanks for the update! I can confirm that with pango-1.49.3-2.fc35 RPMs,
nm-applet does not crash either on list (left click) - also with XFCE here.
