Description:
Writer crashes when I try to set all text to English.
I have a file (originally DOCX, saved as ODT) with 4-5 pages of text (Spanish mixed with English). I want to set the language of the entire document to English.

I can set 'selected text' and 'paragraph' to English, but when I try with "all text", Writer hangs (and I have to kill it).

I tried debugging with GDB: weirdly, I can open the file and work otherwise 'normally', but when I try to open it using backtrace ('lowriter --backtrace') Writer never really opens (although I see the border of a window with the title of the file during a second before it crashes and disappears again).
This may mean I will need also guidance with debugging.
I attach the gdbtrace.log file.

Steps to Reproduce:
This happens when I try to set Enlish as language for All text via Tools > Language > For all text > English.

- it happens only for this file (it works well with a brand-new ODT)
- it happens only for "all text" option. The "selected text" and "paragraph" works fine.

Actual Results:
Also, when I try to debug (lowriter --backtrace) I can not reproduce the problem because in this case Writer does not even start! BUT, there is no problem if I start Writer in the 'normal' ways (eg lowriter from console or Writer in my applications menu)

Expected Results:
Maybe I am doing something wrong with the debugging as well? What else can I do to diagnose this?
