odt that includes images, frames, and columns.

See the attached file, which includes images in frames, which are anchored as characters. These are layed out in 3 columns. If text is changed below the top left image to include an entered newline, LO freezes. Tested with LO 4.4.3.2 and some previous versions, on Linux Mint DE and Ubuntu 14.4.

To reproduce, open the attached file, place the cursor behind the text "Top left image" and press enter. LO locks up, CPU usage goes to 100% (on one processor).
Comment 1 Buovjaga 2015-06-12 10:00:16 UTC
Reproduced freeze by entering new line after "top left image" text. Could not get a backtrace.

Comment 4 Jon 2016-09-20 16:14:34 UTC
This bug is still present in version 5.2.1.2 on Windows 7 when opening the old file that was created with version 4.4.

However, I recreated the file from scratch using version 5 (attached), and this bug is not present in that file.

Repro of comment 4  
i.e., with original test file, after hitting enter, CPU increaes to 30%, LO does not respond (needed to stop program).
With test file created from version 5, no problems.

Maybe this bug should be closed as "worksforme" ?
