Public bug reported:
Binary package hint: rmagic
Using Ubuntu 8.10,
Although the error message comes from libgd, it's due to the code in the
Settings.pm file referred to below. The problem is that this perl script
tries to create a 0x0 image, which apparently worked with earlier
versions of libgd.
I expected rmagic (called from a complex PERL script) to generate a
report from the output of analog. Instead, no report, and the error
message:
gd warning: one parameter to a memory allocation multiplication is negative or
zero, failing operation gracefully
Can't call method "can" on an undefined value at
/usr/share/rmagic/wadg/rm/Settings.pm line 928.
Here is a fix that worked for me, Settings-orig.pm is the version of
Settings.pm which came with the package.
