The short answer is: this assertion is new in 2.2.0dev (see [1]) and before this issue just went undetected, so I don't believe there is anything critical for 2.2.0, except if it is indicative of an underlying behavior that changed between 2.1.x and 2.2.0. I will check this out. Nonetheless, the reason I am excited is that it gives us a chance to improve our error detection (perhaps too late for 2.2.0 but at least for later). Note that in release, assertions are disabled. Scott [1] http://www.lyx.org/trac/changeset/7416064/lyxgit
