[Rhythmbox-devel] Problems with tree DB and libgda

[nixscripter <nixscripter gmail com>]

Hello.

Running both pre-compiled and self-compiled versions of Rhythmbox 0.11.2 
on 32-bit Ubuntu, I get random crashes while playing songs, often while 
changing songs. I decided to dump a couple of cores, and found the 
crashes all occurred in the same place:

Program terminated with signal 11, Segmentation fault.
#0  0x080c275e in save_entry (db=0x8220020, entry=0x85fd670, ctx=0xb28fd34c)
   at rhythmdb-tree.c:858
858             encoded = xmlEncodeEntitiesReentrant (NULL, BAD_CAST 
entry->type->name);

entry->type had a value of zero, meaning this was a null pointer 
dereference. Whoops. I can give an stack trace )or the entire core) if 
you need it, but the call chain appeared to be an attempt to write the 
database of stuff to an XML file.

Not able to follow all the code logic back to where entry->type was set, 
and not knowing enough about the code to insert a hack like setting it 
to ENTRY_TYPE_INVALID if it was zero, I decided to try change databases. 
I tried recompiling with libgda support instead. The result was dozens 
of compiler errors. Most were due to what I would call an outdated 
interface (someone massively changed the rhythmDB interface and forgot 
to update rhythmdb-gda.c and .h files). One, to my surprise, was due to 
an outright typo (a declaration of type G_OJECT_SOMETHING instead of 
G_OBJECT_SOMETHING).

Three questions:

1. Is my crash a known bug?
2. Can I fix it with a simple hack (like ENTYR_TYPE_INVALID)?
3. Is libgda even supported?

Thanks in advance.
