[jira] [Commented] (ARROW-15960) [Python] Segfault constructing a fixed size list array of size 0 with dictionary values

["Joris Van den Bossche (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-15960?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17508191#comment-17508191 ] 

Joris Van den Bossche commented on ARROW-15960:
-----------------------------------------------

Note for future person looking at this: https://github.com/apache/arrow/pull/12588 added a workaround for this in the strategies.py, so while fixing this bug, we should also remove that workaround

> The following example constructing a FixedSizeList array with list size 0 and dictionary values from an explicit None value (extracted from a segfaulting hypothesis test) crashes:

> pa.array([None], pa.list_(pa.dictionary(pa.int32(), pa.string()), 0))
> {code}
