Crash when updating with 1.8

Hi,

After the release of 1.8, the crash reports for TortoiseSVN are already
coming in.

Number one crash is during an update.

In libsvn_wc/update_editor.c, window_handler(), line 1012:

   if (err)
     {
       /* We failed to apply the delta; clean up the temporary file. */
 
svn_error_clear(svn_io_remove_file2(hb->new_text_base_tmp_abspath, TRUE,
                                           hb->pool));
     }

here the hb->new_text_base_tmp_abspath is NULL, which results later in a
null-pointer access exception.

Is it possible to get there without a temp file being created?

I suggest to check for this before trying to remove it:

   if (err)
     {
       if (hb->new_text_base_tmp_abspath)
         /* We failed to apply the delta; clean up the temporary file. */
 
svn_error_clear(svn_io_remove_file2(hb->new_text_base_tmp_abspath, TRUE,
                                             hb->pool));
     }

Stefan
