Bug#940822: silx view crashes on invocation

[Carlos Pascual]

Package: silx
Version: 0.9.0+dfsg-3
Severity: important

Dear Maintainer,

Running `silx view` or `silx test` produces a crash straight away with the 
following output:

```
~$ silx view
malloc_consolidate(): invalid chunk size
KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = python3.7 path = /usr/bin pid = 10504
KCrash: Arguments: 
Alarm clock
```

The expected outcome is a silx view GUI appearing.

I also tested with version 0.11.0+dfsg-1~bpo10+1 from buster-backports,
with the same result.

In contrast, the version 0.11.0 from PyPI (installed in a py3 virtual env with 
pip) 
launches fine.
