The crash occurs in g_strcmp0 in parse_finished as shown below:

static gboolean
parse_finished (ParseThreadData *data)
{

  ...
  ...
		if (g_strcmp0 (channel->url, data->url) == 0) {
  ...
  ...
}

(gdb) p *channel
$1 = {
  url = 0x8900000134 <error: Cannot access memory at address 0x8900000134>, 
  title = 0x1ee0000063e <error: Cannot access memory at address 0x1ee0000063e>, 
  lang = 0x0, 
  description = 0x2a9e4e0 "\220/\303\002",

  contact = 0x0, 
  img = 0x3490000000000 <error: Cannot access memory at address 0x3490000000000>, 
  pub_date = 1293025674299648,

  is_opml = 33, 
  posts = 0x2c57fd0, 
  num_posts = 44388432
}
(gdb) p *data
$2 = {
  dialog = 0x14cebe0, 
  url = 0x292c000 "", 
  channel = 0x2b76390,

Steps to reproduce:

1. Search for "BBC" in podcast search.
2. Select an entry from the results. 
3. Now click on one of the episodes in the below window ( window focus shifts
to podcast view screen, and download starts ).
4. Quickly press 'Add' now.

I repeat these steps quickly ( albiet in some random order ).

Note: This crash occurs less frequently than the one specified in https://bugzilla.gnome.org/show_bug.cgi?id=733499. But, the steps to reproduce remain the same. The point is that I was just trying to sanity check the podcast feature as described above, and it crashed in g_strcmp0(..) also in addition to the crash in 733499.

Is this happening with current git master (ie including commit df6a04a)?

I'm not sure about that.

Since, I'm now running rhythmbox from git with df6a04a, if this issue doesn't pop up in the next few days, this bug can be resolved.

OK.  Please reopen this bug if it happens again.
