crash while submitting post on blogspot

[Fabien V]

After having added a blogspot blog on bilbo.
updating the entry list is working correctly and I can see posts in bilbo.
However when it comes to submit modifications or newposts, Bilbo crashes and here is the backtrace :

The post is still sent to the server...

[Mehrdad Momeny (mehrdad-momeny)]

Hmm, It seems that the problem occurs at fetching post after publish, I have added a check to src, to prevent it to crash.
Hope it works good, If you want to try it, just fetch the bilbo-stable repository src...

[Fabien V (hcooh)]

I just compile the program with the stable + bugfix branch
And the program still crashes when submitting new post or an update (only on blogspot) ...

[Mehrdad Momeny (mehrdad-momeny)]

Please paste the new backtrace here.
I have changed the src, so, I need new results. It works well here!

[Fabien V (hcooh)]

Here is the new backtrace :

Good,

So we need more tests to know why a string copy job has failed!?

I have created a patch, you have to patch your src:

$ cd /PATH/TO/bilbo/root/source/code/
$ patch -p1 < /PATH/TO/test.diff

and then re make install it.

before run, check if debugging output is enabled, run `kdebugdialog` and check the "0 (generic)" item.

then run bilbo from terminal, do the job, and then give me both terminal output and backtrace. :)

Thanks

[Fabien V (hcooh)]

Ok, I did what you said, I joined the backtrace.

[Fabien V (hcooh)]

And here is the output from terminal
