Just committed this patch. It makes things like:

work.
Why now? I don't understand the motivation for this.
My next patch is just going to rip it out again because it will become unnecessary.
Yeah, I noticed it could happen after making the patch, but a segfault on that page made me fix and commit it.
Why did it make plain segfault?
The patch is attached for you to review in detail.
The relevant part is an:
Start_Ofs += i - len;
substituted by a:
Buf_Consumed = BufSize - len;
(if the length of a long line got bigger than 'i', 'i - len' was negative. A strange case triggered by that page, that has really long lines).
How did len get bigger than i? I tried the page yesterday without being able to get a crash. And now I've saved it locally and changed file.dpi to send it 200 bytes at a time, which gives me a long series of normal values when lines get bigger than packets: .. i-len 76 i-len 0 i-len 273 i-len 112 i-len 183 i-len 91 i-len 0 i-len 0 i-len 389 i-len 101 i-len 0 i-len 182 i-len 0 i-len 0 ..
