 Uploaded a sample png logo.

 > Also, which parameters are required for reproducing the crash? Does it
 depend on the main input file or on the logo file?

 I have tried different source format files 720x576 in uncompressed V210
 codec in mxf and pal-DV in quicktime wrappers with the same result.
 Changing the logo to a .jpg worked as did .gif but every .png caused a
 segfault including those with transparency set and those without.

 > Provide the simplest possible commandline which reproduces the crash.

 The commandline already provided is about the simplest to replicate the
 issue. Replacing the '-vf "movie=logo.png [logo];' with '-vf
 "color=red:10x20;' worked.

 The issue seems to be with the "movie" filter and png handling...
