Hello rkomar,
I've got exactly the same issue as immediately above. Juste a black blink when trying to start pbimageviewer.app from the application drawer or by trying to open a .cbz, and an immediate "Segmentation fault" when running it from pbterm.
I'm running the version "pbimageviewer.app-Pro-360+" from 30-Mar-2014 23:36, as downloaded from
http://www3.telus.net/rkomar/pbimageviewer/
I also tried the version downloadable from the first post of this topic which seems to be a bit older, with the same result.
I also added the "626.cfg" file in system/share/pbiv, but that didn't change anything.
My (brand new) device is a:
PocketBook 626 (aka "Touch Lux 2").
Firmware: W626.4.4.693
Release date: 20140404_112517
/proc/cpuinfo: ARMv7 Processor rev 2 (v71)
Please tell if there's anything I can do to help you help us
I looked for but didn't find a Coredump, nor any log (/var/log is empty, gdb is nowhere to be found).
