Bug#728699: libreoffice-calc: calc hangs (100% cpu) on file save sometimes

[Dejan Muhamedagic <dejan@hello-penguin.com>]

Package: libreoffice-calc
Version: 1:3.5.4+dfsg2-0+deb7u2
Severity: important

File Save at times makes the Calc completely unresponsive. Tracing with ltrace
yields nothing, obviously the program enters an infinite loop taking 100% cpu.
The worst is that the file is not saved and work lost. It happened several
times in
a row. The sheet was created with windose excel (xlsx).
