403001 - Thunderbird doesn't filter messages correctly, if header line is wrapped

Status: RESOLVED DUPLICATE of bug 124641

(MailNews Core :: Filters, defect)

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; de; rv:1.8.1.8) Gecko/20071023 Firefox/2.0.0.8
Build Identifier: 

I've setup a mail filter in Thunderbird, which filters away certain messages based on what's in the subject. Recently I noticed, that this filter doesn't seem to work anymore.

Reproducible: Always

Steps to Reproduce:
1. Create filter with the only rule of "Subject" "contains" "Wegwerfbare E-Mail Adresse erfolgreich erstellt"
2. Action: Add Tag "Important" (or whatever...)
3. Apply the filter
Actual Results:  
The message, which I'll attach as a file, isn't filtered.

Expected Results:  
It should be filtered.

As written above, the rule has:

  Wegwerfbare E-Mail Adresse erfolgreich erstellt

As soon as I trim that to

  Wegwerfbare E-Mail Adresse

the filter applies again. I guess that's so, because in the header of the mail, you'll find:

Subject: [TrashMail] Wegwerfbare E-Mail Adresse
 erfolgreich erstellt.

As you can see, there's a wrap after "Adresse" and before "erfolgreich".
