Hello,
tried to reproduce this crash in a Stretch amd64 VM.
It wants to open the directory "maps":
benutzer@debian:~$ strace -f zatacka 2>&1 | grep maps
open("maps", O_RDONLY|O_NONBLOCK|O_DIRECTORY|O_CLOEXEC) = -1 ENOENT (No such
file or directory)
Therefore a null pointer is handed to readdir.
Until 0.1.8-2 this directory got created and the file map1.jpg installed as
maps1.jpg:
--- 0.1.8-2/zatacka-0.1.8/debian/rules 2018-09-10 18:43:42.000000000 +0200
+++ 0.1.8-3/zatacka-0.1.8/debian/rules 2013-05-02 17:03:14.000000000 +0200
...
- install -m 0644 maps/map1.jpg
$(CURDIR)/debian/zatacka/usr/share/zatacka/maps/maps1.jpg
Since 0.1.8-3 the package does not contain the whole directory.
Yet the file map1.jpg is conatined as map1.jpg, but the application
tries to open a directory "maps".
Kind regards,
Bernhard
