Re: question on g_list_insert_sorted () usage

["Aar Em" <itsme_515 hotmail com>]

Hi,

Many thanks! I think I should let you know that g_list_append works fine, 
except that it does not give me a sorted list by ctime (creation time). org. 
The debugger crashes just after entering the function at the point of the 
"return statement".

Program received signal SIGSEGV, Segmentation fault.
0x0804db2b in compare_ctime (a=0x8ef5ae0, b=0x0) at count.c:19
/usr/local/aarem/Desktop/gbuffy-0.2.6/count.c:19:339:beg:0x804db2b

Btw, I am sorting by the ctime, the creation time of the messages in the mh 
folder.

Many thanks,
aarem
