Is this a plugin dissector or normal dissector? If it's a plugin, it
seems you're not the only one experiencing this problem, although I
highly doubt that it's a Wireshark bug. There have been some changes to
the plugin API somewhat recently and I think your problem may be related
to that. You might try first to re-read the most recent README.plugins
and possibly even reviewing the following tutorial:
http://www.codeproject.com/KB/IP/custom_dissector.aspx. In addition,
it's probably a good idea to compare your plugin files with the
Wireshark built-in plugin files.

Subject: [Wireshark-dev] 0.99.8 col_append_str fails
I am writing a dissector for a custom protocol and found that I am
unable to add additional information to the INFO column. See the
following code:
if (check_col(pinfo->cinfo, COL_INFO)) {
col_append_str(pinfo->cinfo, COL_INFO, " more info");
}
It appears that after the initial setting of the column, pinfo->cinfo is
no longer writable. That is
col_get_writable(pinfo->cinfo)
always returns false. It still returns false even after I run:
col_set_writable(pinfo->cinfo, 1);
Has anyone else run across this? I thought I had this working for
another dissector on 0.99.6 but I don't have that code with me right
now.
Thanks for any thoughts, comments, ideas -- Jason
