[ 1589334 ] segfault for filenames without a dot #4

Closed GoogleCodeExporter closed 9 years ago

Roger Luethi - rluethi(sf)

In pgedit.cpp:797, strrchr() will return NULL if the
given filename is lacking a dot. but the code doesn't
check for it.

Therefore, feeding the program a filename without a dot
results in a segfault as the subsequent strcmp()
expects valid pointers.

It uses the extension to recognize the filetype. To fix requires a bigger change
related to all the obsolete filetypes it used to be able to read. This is not a 
high
priority right now.
