Probably. M. Stahl has done quite a number commits related to table crashes I
reported. It's pretty stable now days (except for aSwFrame::IsLeaveUpperAllowed
crash, you can get with bad luck). However, it got a little worse in this area;
finding a layout; some kind of infinite loop? 
This a nice example (except it fixed after copy paste) Instead of me trying to
generate some artificial bug doc showing the issue (added a few reports in see
also). 
- There a cases where table rendering stops; with tables going off page.
- Table rendering is 'unstable'. Click inside a table, and whole table
splitting while change.
- Tables splitting, but on every load/versions differently (a document can have
500 or 530 pages.. depending how tables are split; mostly lot of pages + quite
number of footnotes, heading etc.
- This table of if issue; infinite loop :-)
- Table who actually finish after spending quite some time doing shrinking,
FindRowFrame (as seen in the basic Very Sleepy profile)

All happening with complex documents. Table cross pages, merged cells,
footnotes, embedded tables. Especially combining everything, footnotes in
embedded (merged) tables.
