Hello
Before filing a bug report, I want to make sure it's not a problem of my local
(eventually bad) compilation, as it seems to have incurred from a discussion
on IRC yesterday.
When using the file selector from any application (tried mostly kmail and
kate), trying to select a file for attaching (kmail) or opening (kate) or
whatever, I get a crash in the Arts::Dispatcher.
This behavior started (certainly) after compiling, on Jan. 18, the latest CVS
(thus immediately after 3.2rc1 tagging). It still does crash with the
compiling of last night (CVS of around 22 Jan, 3AM GST). I use the
ARTS_1_1_1_RELEASE branch or arts. I'm pretty sure that if this is not a
local problem with my copy of the code, then it's a very ugly bug that exists
in the 3.2rc1 release. Needless to say it would badly need fixing.
Here is the line put out just before the crash (sorry, I can't do attachments,
so I have to pase. Broken lines are resulting):
kio (KDirWatch): Setup Stat (freq 500) for /home/ctibirna
kmail: dispatcher.cc:450: static Arts::Dispatcher* Arts::Dispatcher::the(): \
