It's not out of the question at all. In the the future though.

oops disregard last comment

Can't reproduce with this description with beta 7...
However, I can reproduce 291675.

Open file, place cursor before first word of second paragraph, hit enter. it crashes.
I'm unable to geat a useful backtrace, but I will attach a file where it happens. This happens every time.

crashing file

unfortunately even with that document and doing as you describe it doesn't crash for me so i really need someone who can produce backtraces

This is the best I've been able to come up with so far,

Different crashing file

Attaching another file where this happens. Simply open using words, the cursor should be at the beginning of the first paragraph. Hit enter. Crash.
As a bonus this file will make Words use 100% of the CPU and become unresponsive if I try to insert a character in the middle of a paragraph. (But that is a different issue, should I file a new report?)

I can not reproduce crash, but I can reproduce the unresponsiveness when entering text, so yes please open another bug for that

I can reproduce the crash in beta 6. Words crashes pressing Enter twice while cursor is inside a paragraph or with just one pressure when placing the cursor at the beginning of a text paragraph.

If the cursor in on an empty line, it is all ok.

My crash log:
http://paste.kde.org/199976/

I'm sorry but without debugging symbols those backtraces are not worth much to me. Could you please see if you can either install debugging pacage for calligra or build from source.

boudewijn or bugsbane, maybe yo guys could test with the files linked in recent comments ?

*** Bug 293976 has been marked as a duplicate of this bug. ***

duplicate bug https://bugs.kde.org/show_bug.cgi?id=293976 shows the bug is Qt related

it's the line in KoTextEditor::Private::newLine:
caret.setPosition(startPosition);

that makes Qt crash, Presumably because Qt fails to register that the block layout has become invalid.

I'll try writing the code a bit different to see if we can work around, but being unable to reproduce myself I'll be working blindly

Compiled master from git; unfortunately the work around doesn't work. Still crashing.

Ok thanks, it's a Qt bug, so closing as upstream (meaning Qt)

I see it's closed, but just for the sake of completeness, here's the best backtrace I've (finally) been able to come up with :
