This issue may be down to the application in question dynamically linking to the wrong version of the [libJPEG.dylib] library (it's also possible the correct version has been overwritten/modified). As explained in another question it is a problem that can occur when an application alters environment variables that control dynamic linking library location (e.g. On MacOS: DYLD_LIBRARY_PATH - more info see man dyld; On Linux: LD_LIBRARY_PATH - see man ld.so). It may be down to other factors such as dynamic link library config files but they have a system wide affect. You'll need to locate the variable setup in the application files and change it so that it prioritises the system paths e.g. (for MacOS):

export DYLD_LIBRARY_PATH=/usr/lib/:ADDITION_LIBRARY_PATH_LOCATION
