All I get is an empty rectangle - I did install fantasque Sans in ubuntu. What font are you using in Konsole? OK I had to reboot for the Fantasque to show up - even w/ that as Konsole's font, all I get is an empty rectangle. I'm on Qt5.9 though. Created attachment 108225 [details] attachment-449-0.html I am on QT 5.7. I use Sabayon, a Gentoo based distro (5.7 is the latest available on Gentoo).

New crash information added by DrKonqi
konsole (17.08.2) using Qt 5.9.2
I just updated my QT to 5.9.2 and the crash is still there. Konsole is now 17.08.2.
As before it crashes when I run:
perl -C -E'say "\x{1F3F4}\x{E0067}\x{E0062}\x{E0065}\x{E006E}\x{E0067}\x{E007F}"'
I also backed up konsolerc and it crashes as well, so it doesn't seem related to the font I was using.

Tried the command from comment #4, and it displayed a Waving Black Flag emoji. No crash. Are you using a color font for emoji? I can now report the issue has finally been fixed. This is on Konsole 17.12.0 and QT 5.9.3. QT 5.9.2 and 17.08.2 it was not working for sure, but I checked again today and it no longer crashes! A little more info on the original cause/replication I did previously: Also there have been no changes in my fonts and I don't use color fonts. It does not show any icon when I run it, but I may not have the fonts installed. Though that is besides the point and the issue I was having was viewing text documents with less was causing my entire Konsole process to segfault! (The perl command was just replicating it). I noticed the crashes semi-randomly, though I could produce it every time viewing one of the files here: https://www.unicode.org/Public/emoji/5.0/ so I created a perl command print the offending codepoints to trigger the crash for a bug report. If you have any more questions let me know, but I'm going to close it as resolved. |
Application: konsole (17.08.1) Qt Version: 5.7.1 Frameworks Version: 5.38.0 Operating System: Linux 4.12.0-sabayon x86_64 Distribution: "Sabayon Linux amd64 17.10" -- Information about the crash: - What I was doing when the application crashed: perl -C -E'say "\x{1F3F4}\x{E0067}\x{E0062}\x{E0065}\x{E006E}\x{E0067}\x{E007F}"' It is reproducible every time for me. See https://emojipedia.org/flag-for-england/ The font I have set is Fantasque Sans, though I don't know if that matters. The perl command above prints out the 'England' flag. It is a new emoji and it's causing Konsole to crash every time it was seen. Either printing it out with perl or by using less on the UCD (Unicode emoji data files). The crash can be reproduced every time. -- Backtrace: Application: Konsole (konsole), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".
