Hello everyone,

for a while now, I am happily using TeXmacs under Archlinux (thank you 
for this nice program).

Sadly, since a recent system update I am not able to start TeXmacs 
anymore. Running texmacs -d in the terminal results in following error 
message:

-Start error message-

-End error message-

My first guess is that this is related to an update of Qt5. Both, 
because I remember that Qt5 was in the list of updated packages (there 
were multiple updates to the qt5-base package and probably other qt5 
related packages in the last days) and because of the "widget should be 
attached" message. I already tried rebuilding TeXmacs (with the PKGBUILD 
of the official arch repo), but the problem stayed. I am willing to do 
more tests, if you need additional information, and of course I can test 
any patches on my system.

Thank you again for all your work on TeXmacs!

Jan

PS: Please let me know, if these kind of bug reports should better be 
posted on this mailing list or on the dev list.
