[php-maint] Bug#843386: php7.0-gd: wrong libwebp dependency

[Samuele Battarra]

Package: php7.0-gd
Version: 7.0.12-1
Severity: normal

Dear Maintainer,

every time I run php or sessionclean is run from cron, I get this error:
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/gd.so' - libwebp.so.5: cannot open shared object file: No such file or directory in Unknown on line 0

the problem is than php7.0-gd depends only on libwebp6, but uses also libwebp5

$ ldd /usr/lib/php/20151012/gd.so | grep libwebp
libwebp.so.6 => /usr/lib/x86_64-linux-gnu/libwebp.so.6 (0x00007f3f2c439000)
libwebp.so.5 => not found

installing package libwebp5 solve the problem
