类型错误使用SORL-缩略图和枕头

Question

IM使用SORL-缩略图Django和我发现了一个错误：

    return encoder(mode, *args + extra) 
TypeError: integer argument expected, got float 

我不知道这是否是一个SORL-缩略图错误或枕头错误。 我也不知道哪个参数失败。我怎么解决这个问题？ 我应该开始调试吗？

谢谢！

编辑1：

发起者debbugin和最后的参数是：

encoder = <built-in function jpeg_encoder> 
args = ('RGB',) 
mode = 'RGB' 
encoder_name = 'jpeg' 
extra = (95, True, 0, True, 0, 0.0, 0.0, -1, None, '', '') 

编辑2： 在/usr/local/lib/python2.7/dist-packages/PIL/Image。 PY在保存在行1685： save_handler（个体经营，FP，文件名） - 参数是：

fp = <cStringIO.StringO object at 0x7f0d4f3ae688> 
format = 'JPEG' 
self = <PIL.Image.Image image mode=RGB size=75x21 at 0x7F0D4F2079E0> 
filename = '' 
ext = '' 
params = {'compression': 0, 'dpi': (0.0, 0.0),'optimize': 1, 'progressive': True, 'quality': 95} 
close = 0 
save_handler = <function _save at 0x7f0d4f13d230> 

他们看起来正常的我，也许是一个枕头错误。

实测值的原因：

文件类型：PC位图，Windows 3.X的格式，285 X 78×24 MIME类型：image/X-MS-BMP 建议的文件扩展名（多个）：BMP

该文件是BMP，而不是JPG。

对不起。
