Description Malte S. Stretz 2009-07-20 13:14:33 UTC
Application that crashed: konqueror
Version of the application: 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2))
KDE Version: 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-13-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
This bug is around sice KDE 4.0 or so and I reported this as part of bug 177245 already, but that one is a collection of various bugs (some fixed), so here's an extra one just for this (100% reproducable) crash.

Bug 198494 seems to be the same bug as well, I didn't file this one as a dup because I've got reliable steps to reproduce it, I hope somebody finally fixes it *sigh*

To reproduce, do the following:

1. Soup.io is a tumblelog you can try at http://try.soup.io/ without creating an account.
2. Go there.
3. Skip the welcome screen.
4. Click the plus sign at the bottom left.
5. Choose Text (the first option)
6. Click into the test input.
7. Everything still fine.
8. Type something, anything.
9. Notice that the input jumped down by one line, a line break was inserted.
10. Go to that first empty line.
11. Press Del to remove the line break.
12. Boom!

Backspace to delete the newline has the same effect.

Comment 1 Dario Andres 2009-07-21 02:46:21 UTC
I can reproduce the crash using the detailed steps here using:

Qt: 4.5.2 (KDE-Qt git commit 46a247a2c9a8c0c4456a02f6a0922d859d88fe76
        Date:   Fri Jun 26 13:45:37 2009 +0200)
KDE: 4.3.61 (KDE 4.3.61 (KDE 4.4 >= 20090717))
kdelibs svn rev. 999250 / kdebase svn rev. 999250
on ArchLinux i686 - Kernel 2.6.30.1

BTW; bug 198494 looks also related.
Comment 2 Viacheslav Tokarev 2009-07-21 19:47:53 UTC
There was a problem with inserting text into layout like following: <body><div contenteditable=true><br>   </div>; We incorrectly found upstream/downstream equivalent positions at borders (e.g. position(br, 0)). And thus inserted text into incorrect place. It's fixed by commit in my soc branch: http://github.com/vtokarev/khtml-soc09/commit/6b41fafabed826b1db31821a48eacdd2ea943b39
It will be merged later on into the trunk and will be part of 4.4 release.
Comment 3 Malte S. Stretz 2009-07-21 21:08:19 UTC
Cool.  Would be great if it could be backported to 4.3 as well.

Comment 8 Justin Zobel 2020-12-03 22:44:54 UTC
Thank you for the report, Malte.

As it has been a while since this was reported, can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved.

I have set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved/worksforme" when you respond, thank you.
Comment 9 kavol 2020-12-07 12:21:27 UTC
not the same issue, however, simply visiting https://www.tiny.cloud/ with KHTML (not WebEngine) causes Konqueror to enter some endless loop, so I can't even get to testing the editor ...
Comment 10 Bug Janitor Service 2020-12-22 04:34:29 UTC
