Bug ID: 100079
Summary: FILEOPEN of .docx file drive CPU usage, almost freezes
Writer
Product: LibreOffice
Version: 5.0.4.2 release
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: libreoffice-bugs@lists.freedesktop.org

.docx file that pushes CPU usage, nearly kills Writer
The submitted file is from the NSF web site (public). It is 4 pages of text
with some decoration, but the file size is 5 MB. On opening this file, the
initial load takes minutes with CPU usage near 50% (90%+ on one core). All
Writer functions stop until this file finishes displaying.
System Monitor (openSuse 42.1, 64-bit) shows that "X" is the top activity by
CPU percentage (24%, or one thread of a dual-core CPU). soffice.bin takes
almost as much, and produces a zombie process when I try to kill LibreOffice.
Tried to delete the decorations (possibly in the header), but the system was so
slow that I couldn't.
Managed to save this file as .odt and .doc but upon opening those formats found
the same problem.
