Re: [Texmacs-dev] a test for the Qt crash under X11

[Alvaro Tejero Cantero]

Hi,

I just compiled menu-test. No crash whatsoever.

With freshest TeXmacs-qt from SVN I don't have problems either. I
didn't try oxygen (I don't have KDE) but I tried several qt themes
accesible through qtconfig-qt4: cleanlooks, motif, windows and
plastique. If there is interest, I can download KDE and try the oxygen
theme.

My system here is Ubuntu 8.10 64 bit.

Linux eco 2.6.27-9-generic #1 SMP Thu Nov 20 22:15:32 UTC 2008 x86_64 GNU/Linux

My QT4 libraries are version 4.4.3, e.g.

ii  libqtcore4                                 4.4.3-0ubuntu1.1
                             Qt 4 core module

Keep up the good work!

Álvaro.
