I upgraded a great deal of packages today after 5-6 days without doing so. As a result, keyjnote 0.10.1 refuses to render pages using poppler's (0.6.1-r1) pdftoppm (v3.00). Here is a typical output: ===== Welcome to KeyJnote version 0.10.1 Detected screen size: 1024x768 pixels Using conventional power-of-two textures with padding. Error: pdftoppm produced an unreadable file (page 1) ..... ===== I use a mostly stable AMD64 system, and last week keyjnote-0.10.1 was working flawlessly. Any ideas? Thanks in advance. Reproducible: Always Steps to Reproduce: 1. Launch keyjnote 2. 3. Actual Results: keyjnote does not read pdftoppm's output: ====== Error: pdftoppm produced an unreadable file Expected Results: keyjnote renders the PDF page My emerge info: ======== Portage 2.1.3.19

There is a patch for keyjnote available in a Ubuntu bug report for correcting this. See https://bugs.launchpad.net/ubuntu/+source/keyjnote/+bug/148070
Thanks for your help. In the meantime I had contacted the author, Martin J. Fiedler, who very kindly told me: ==== poppler's pdftoppm implementation is incompatible to the original Xpdf one; in particular, the filename generation pattern has changed. Unfortunately, I didn't come around to fix this problem yet, though the fix is easy: You should find the string "-%06d" (without the quotes) somewhere in KeyJnote. Replace it by "-%02d" and everything should work again, at least for presentations between 10 and 99 pages. ==== I did as he suggested and everything is back to normal for me. I didn't try the patch in Ubuntu's forum since it seems to change the rendering engine from Xpdf to ghostscript, or so I interpret from its code, whilst the fix suggested by the author himself seems to work pretty well.
this should be fixed in keyjnote-0.10.1a.
