I got an assert:

assert(!"SfxUndoManager::Undo: not possible when within a list action!");

With a 6.2 master debug build (7ad1c45c3ef07147681c9f084ae2d0936a2438fe) / Windows 7.

Probably bug 117749

Regression introduced by https://cgit.freedesktop.org/libreoffice/core/commit/?id=83243003b46dfb258c2b41049b0e1cb82a2d7ddb, which is the same as in bug 117749

*** This bug has been marked as a duplicate of bug 117749 ***

@Xisco Faille
Is this really a dupe of bug 117749? Of course, when interpreting it as comment 5. However, de crash happens when pasting, without the undo part. BT differs to

Just to be sure, have you cleaned your profile?

I can't reproduce it in

Version: 6.2.0.0.alpha0+

Also crashes with 6.1 beta2 (x86), but not with x64 / Windows 7.

tdf#72942 Do not overwrite styles from the inserted doc

CPU threads: 4; OS: Linux 4.13; UI render: default; VCL: x11;

so it seems to be a only Win problem

gdb bt

On pc Debian x86-64 with master sources updated yesterday, I could reproduce this.

I attached bt with console logs

(In reply to Julien Nabet from comment #13)
Did you use the steps of comment 0 or comment 5. The BT looks like comment 5 (and fits bug 117749). This bug probably limited to x86 builds (see comment 10)

I used your description comment 0.

Forgot to tell that it crashes after 4. CTRL+SHIFT+V, when choosing RTF and click Insert.

Not a WriterMultiListener-regressions based on comment 11

The commit of "Do not overwrite styles from the inserted doc" results in "don't overwrite or add styles in the inserted doc", but the styles are still set on the paragraphs, and as they don't exist various exceptions are thrown, causing the problem.

PICTURE: paste without error but not exactly

I attached a picture. No crash on CTRL+SHIFT+V, but the new document looks different by the original document (I don't know if this is a problem).
