I just compiled LyX 1.5.2svn to test the fix for bug 4133. But now LyX crashes on every longtable:
Open the Embedded Objects manual and go to section 2.6.2.3. You can se that Table 6 is broken as the Name field appear right beside the table. When you now scroll a bit LyX crahses. I also cannot create PDF output any more, get lots of LaTeX-error about misplaced align character instead.
I don't have enough time right now to go deeper and find the reason, but as this bug makes it hard to use LyX 1.5svn I vote for reverting the bug fix until we found a better solution.
regards Uwe
