Updating the description to make clear that it appears only in a presentation, with mouse select (keyboard selection OK, unless followed by copy to verbatim as Miguel noted). Also, I find that selecting a single item is enough to get a segfault, contrarily to what stated in the original report.

The attached file causes TeXmacsQt to crash if at least two items of the enumeration are selected. This is caused by exec_verbatim() (called automatically in Qt while setting the selection), which enters a deep recursion. By commenting the line

inside edit_select_rep::selection_set(), the text may be selected without TeXmacs crashing.

However The bug can still be triggered by then clicking Edit->Copy to->Verbatim, so this is not Qt specific, but due to exec_verbatim().
