LibreOffice Writer hangs when deleting text in attached test case

[nitrogen]

Deleting a few lines of text from the attached test case document causes LibreOffice 4.0.2-0ubuntu1 to hang.

This minimal test case document was reduced by hand from a full, working document that also experienced the same hang. The text in question contains endnotes, columns, and headings, most or all of which had to be present to reproduce the bug.

Thread backtraces, with debugging symbols, are included in the attached oobug.txt file.

Steps to reproduce are also included in the attached screen shot animation.

Steps to reproduce:
1. Open "test case 6.odt" in LibreOffice Writer
2. Select the three lines of text in the right column
3. Press the Backspace or Delete key to erase the text
4. The text is not erased, and all open instances of LibreOffice hang

nitrogen, does Writer ultimately crash, or does it just stay hanging?

Status changed to 'Confirmed' because the bug affects multiple users.

I have a multipage document with 2 columns and whenever I select text that goes from one column to the other it seems to just stay hanging and turns gray and cpu maxes out. I am not very patient so I force close the document. Let me know if there is anything I can do to help provide more information. It seems fairly reproducible. Peace - Anthony

Anthony, it would help immensely if you filed a new report following https://wiki.ubuntu.com/LibreOfficeBugWrangling .
