True, but I don't interpret that to be OP's objection.  Gscan2pdf does 
solve the problem, at least paritally / mostly. 

I tried it on my system.  While 'convert *.jpg result.tif' succeeds in 
creating a multipage tiff, but 'convert *.jpg result.pdf' fails with 
"Segmentation fault".

But I am able to use gscan2pdf to import large number of jpegs write 
pdf.  I say the problem is only "mostly" solved because it does not 
appear that you can feed a group of images from a command line and 
automatically spit out a pdf.  (Not really surprising for a GUI tool)

If a command line soltution is needed, maybe make the intermediate tiff 
and then use tiff2pdf.  Try the -n switch if you get weird colors, the 
-j switch to recompress and -q <qual> to set jpeg compression if you 
don't like the default.  Oh, and the default output is stdout, so you 
need an explicit -o <filename>.

As you can tell, I fiddled a little.  I could not figure out how to get 
tiff2pdf to take input from stdin  anyone who's had success can chime in.
