Litehtml in Claws-mail takes ages parsing a specific HTML e-mail #301
Description
The following file is HTML (github won't let me attach as .html) extracted from an e-mail.
a.txt
When opening it in claws-mail with the litehtml viewer, it takes ages (several minutes!) to show anything, and the mail client looks like it's hung.
When opening it in litebrowser, it's faster, but still seems to take a long time.
Is there a chance that you could investigate on your end if anything might explain why it's so slow?
The claws-mail stack trace looks as follows:
