I tried a couple times and did not get a segfault. But I did notice in
looking over the
backtrace that you have the documents in a Dropbox folder. Do you still
get the crash
in other directories?
This line
#50 0x000000000120b2f2 in lyx::frontend::Alert::prompt (title0=L"Create new
document?",
question=L"The document
/home/scott/Dropbox/Inbox/lyx_mwe_sigsegv/doesNotExist.lyx does not yet
exist.\n\nDo you want to create a new document?", default_button=0,
cancel_button=1, b1=L"&Create",
b2=L"Cancel", b3=L"", b4=L"") at
/home/scott/lyxbuilds/master/repo/src/frontends
is a little strange. This is asking to create the master document for
question1.lyx, which has
just been pasted. But its master should be the document into which it is
being pasted. I do not
get asked that question, which is probably why I do not see the crash.
Otherwise, the fact that this happens with *separate* LyX instances
makes me wonder whether
there is not some problem in Qt somewhere.
