[Gnobog-devel] SIGSEGV in real_new()

[Detlef Vollmann]

Hi,
compiling went fine now, cmdline runs, and so I went on to run
the GUI...
I got the following messages:

dv: > /test/bin/gnobogtest
error: failed to load external entity "gnobog_document.dtd"
/usr/tmp/gnobog-test/share/gnobogtest/default_prefs.xml:5: validity
error: Validation failed: no DTD found !

            ^

/bin/tar: Error exit delayed from previous errors
error: failed to load external entity "gnobog_document.dtd"
Segmentation fault (core dumped)

I can probably ignore all the tar messages.
I can probably also ignore the XML DTD and validation errors.
I'm not so sure about 'sh: Wg@: command not found'.

I definitely can't ignore the segmentation fault ;-(

The debugging version gives as last messages:

LgbItem-Message: Creating new item from xmlnode 0x81112d8
LgbItem-Message: Initializing object LgbItem

And gdb gives as stack dump:

I must say that I have no idea what's going on here.
If you need any more info just mail again.
