i just patched to 3.2.6 and i have the exact same issue. perhaps its an error in 
the patch only? and thus escaped testing?

btw... i have inline html turned on for this horde/imp install and now the 
inline html is not displaying, in fact only a blank message with the "unnamed" 
text/html attachment which when i click on I get the same error above.

yes i can:

string(9) "text/html" bool(false)
Fatal error: Call to a member function on a non-object in 
/home/httpd/vhosts/webmail/horde/imp/view.php on line 82

(of course it was line 79 before i added those var_dumps)

other info you may (or may not) find useful:
OS: RHEL3 (Taroon 2)
Apache/2.0.46
php-4.3.2-11.1.ent

anything else i can help with?
